Can I give this 6 stars, please?? This is the book you wake up thinking about and spend all day wishing you could read instead of working! The characters were flawless, the plot was intriguing, and the pacing was perfect.
​Aubrey and Alex are the couple everyone will root for—the perfect example of how sometimes the third time really is the charm! I love how Brittney keeps her books relevant to modern day with references to things like AI, while still keeping the grounding of an age-old love story. And the cameos! Brittney wove in past characters seamlessly; getting to visit them was such a treat and made my heart so happy.

INTO THE DEEP by BRITTNEY SAHIN ⭐️⭐️⭐️⭐️⭐️

Into The Deep is the second (#2) book in the DELTA SHIELD SECURITY series. Release date: February 24th 2026.

Audrey Langston is trying to settle into a new life after lies, betrayal and deceit turned it upside down. All she wants now is to live quietly and keep her son safe and happy. She’s done with love, done with relationships, done with men.

When her home is invaded and she is attacked it appears that it wasn’t random break in, someone is watching her, so she feels she has no option but to call on her new found brother and his Delta Shield friends to protect her and her son.

Alejandro Rodriguez is still recovering from his ex wife’s betrayal, a betrayal that almost cost him his life, so despite his undoubted attraction to his teammate’s captivating sister he is determined to treat this as just another mission.

The pair grow closer whilst desperately trying to keep their relationship platonic, but as danger closes in and twisted, multilayered threats rise, Alejandro realises that he’ll put everything on the line to keep Audrey and her son safe…..

—————————————
** Whilst this book is easily read as a standalone, I highly recommend you read the first 5⭐️ book in the Delta Shield Security series AGAINST ALL ODDS as it will you a greater insight into the Delta Shield operators and their characters **

This highly anticipated second book in New York Bestseller, Brittney Sahin’s Delta Shield series certainly didn’t disappoint! What a start to 2026!

I am constantly amazed at Brittney’s ability to weave highly complex yet easy to comprehend stories. She really is the queen of military romance!! I love a book that makes me THINK, and that’s exactly what this delicious read does. With plenty of threads, twists and turns, where every corner you turn another snake slithers out of the woodwork, Into The Deep is a pulse raising, edge of your seat, suspenseful military romance.

One of the things I particularly enjoyed about this book is that there isn’t TOO much spice. Yes, there are open door scenes, but they are tastefully done and used only to show the progression of the main characters relationship. Alex and Audrey’s relationship is a lovely slow burn, threaded throughout the action and suspense, which makes it relatable and believable. None of the spice is used for shock value and that was appreciated by this reader.

Alex and Audrey are a well matched couple, both kind, thoughtful and giving. Both always putting others first. Although there are a couple of misunderstandings between them, their willingness to be open and honest with each other means there isn’t too much angst which is good considering the trials they face throughout this book.

The storyline? WOW! That’s Pretty much all I can say. I love when authors challenge readers, make us think and try to work out the perpetrators. I literally couldn’t put this book down!

I Also really enjoyed seeing characters from previous series popping up and flexing their protector muscles !! You can’t help but get tingles when they are all working together.

There are also a plethora of delicious new side characters, and I can’t wait to learn more about Hollis,Trevor and maybe Eden. Hollis in particular is fascinating and I hope we learn more about her prior ‘adventures’.

I read an ebook copy of this book (and can’t wait for my physical copy to arrive squeeeeee) at just over 400 pages and with a gorgeous male cover I really can’t recommend it enough.

If military romance is your thing and you like edge of your seat action then I recommend you dive right in!

Thanks to Brittney Sahin and NetGalley for the free ARC. All opinions are my own in the following ARC Review.

Synopsis: While dealing with the death of her second husband, Audrey narrowly escapes a break-in at her home. Alex is sent ahead to protect her, and quickly learns the attack was not random. It’s suspected Audrey’s late husband faked his death after uncovering classified information about a disbanded clandestine special-ops group. His discovery, and threat to expose it, made him a target of his own former team, who now believe Audrey is the key to retrieving the intel he hid as a failsafe. To flush out the threat, Alex and his team, including Audrey’s brother and the father of her son, stage a high-risk undercover trap using Audrey, where she is to be captured in the process. Alex and the team launch a full tactical rescue, defeat the rogue operatives, and secure the intel before it can be weaponized against the government. In the aftermath, common hurts and understanding, turn into love. Alex and Audrey marry, reveal a pregnancy, and look forward to building a life together shaped by safety and truth after surviving deception and betrayal.

Thoughts: This was another great read and a solid addition to the Brittney Sahin universe. I loved how intricately connected this book was in particular. Audrey and Alex both have complicated pasts, and it was impressive to see how even the loosest connections were thoughtfully woven together. I really enjoyed how sweet Alex and Audrey were with each other. Their severe past hurts allowed them to see themselves in one another, forming a deep, unspoken bond rooted in shared understanding. And while there wasn’t a love triangle, it almost felt like one at times because of Audrey’s interactions with her first ex-husband and father of her son. I did think there was a bit too much page time between these two, especially having such emotionally intimate scenes. It made Alex unsure of himself in moments, and I would’ve preferred to see more one-on-one scenes between him and Audrey instead. Alex truly was a great guy, and it was refreshing to see how accepting he was of everyone in Audrey’s life, including her ex. Even better, having respect and openness being reciprocated. I can genuinely see Alex and Audrey’s ex becoming good friends in the future. Brittney also teased what I hope turns into a potential new series revolving around Hollis’ family. I have to say learning about them intrigued me the most. I’m also looking forward to seeing who Gwen ends up with. Can’t wait for Reed’s book next, he’s definitely a favorite.

⭐⭐⭐⭐⭐ | 🌶️🌶️
Perfection!

If there were ever any doubt that Brittney Sahin is the undisputed Queen of Military Romantic Suspense, Into the Deep puts those doubts to rest. From page one, I was hooked. This is the kind of book you don’t rush—you savor every word because Brittney Sahin’s storytelling is that masterful.
Her ability to pull readers into the hearts and minds of her characters is unmatched. Alejandro and Audrey feel real, layered, and unforgettable. We first met them in Against All Odds (Delta Shield #1), and while this story can absolutely stand on its own—as all of Sahin’s books can—reading book one enriches the emotional depth of their journey. One of my favorite things about Brittney’s writing is how she seamlessly weaves in characters from previous books. Their appearances feel like catching up with old friends, and they’re always a welcome treat.

Without revealing spoilers, Alejandro is a man shaped by loyalty, duty, and past heartbreak. Jaded but honorable, he’ll do anything to protect his country and the people he loves. From the moment he meets Audrey, he senses a second chance at something real. Audrey, a strong and independent woman navigating life as a twice-married mother, never expected to fall again—especially not so deeply or so soon. But her attraction to Alejandro is immediate, and their connection feels fated.

One of the aspects I appreciated most in Into the Deep is the pacing of their romance. Instead of relying solely on physical attraction, Sahin gives us a beautifully developed emotional relationship. There’s banter, flirting, and a few spicy moments, but the focus is on trust, vulnerability, and two souls choosing each other. Alejandro’s faith is another layer that adds sincerity and warmth—his belief that God was watching over them was both moving and perfectly woven into the story.

Brittney writes. I read. That’s the deal—and once again, she’s delivered a phenomenal, heartfelt, action-packed romance. I can’t wait for everyone to dive into this one.
And yes… I’m already counting down the days until we get Reed and Holli’s story!

Another hit by Brittney Sahin, this is the second in the Delta Shield Security. This book is about Alejandro (Alex) and Audrey. Audrey is the recently discovered sister of Ryder Book 1 in the Delta Series, which is how Alex met Audrey. Audrey is in the process of divorcing her husband Mitch, so she moved closer to her ex husband Trevor with her son. Suddenly Audrey is attacked, and Trevor calls Audrey's brother Ryder. Which is how Delta Shield Security got involved. It seems Mitch has come back from the dead and put Audrey in danger and Delta team is doing everything to help her. When Alex and Audrey first met they had an instant attraction which only gets stronger the longer they are in each others company. As they look into the deception Mitch set in motion, they realize that not only their lives are in danger but possibly other operators. The is a time limit to when they can grab confidential from a secured vault that only Audrey can open using both her and Mitch's wedding bands. If they don't solve the mystery soon Audrey could be killed and secret operators exposed. Alex and Audrey both need to get over past betrayal, Alex from his ex wife who almost killed him and Audrey from her second husband Mitch. As they get closer to solving the mystery, Audrey also discovers her best friend Hollis was lying to her but to keep her safe based on her true identity (she is a secret operator). Brittney has a way of writing about her characters that makes you feel that they are actually real. She also develops strong secondary characters that make you want them to get their own books so you can learn more about them. This book dives into relationships after divorce, how to heal from betrayal when true love is involved. This book is excellent, you don't need to read the books in order however I would strongly recommend you do as you get to know the characters and have a better understanding of them when their book gets written. Pick up this book ASAP and start reading today.

Into The Deep by Brittney Sahin is a book that delivered so much more than my very high expectations for it. The book is the second of three in her Delta Security series and not only continued the high standards of the first book, Against All Odds, but took those standards even higher.

She weaves together characters in a story that instantly leave you feeling invested in their circumstances, relationships, and evolving suspense. She creates scenes and descriptions that make you feel as though you are present for the action. The descriptions are never too much but create a perfect setting. As I read, found my heart raced, I swooned, and I felt every emotion from anger and frustration to pure joy and laughter. This book brought all the fun and action delightfully from start to finish. The trope and developing characters are perfect. The only thing better was the author throwing in a few familiar names and characters from another series or two she wrote. It’s like visiting or checking in on old friends. My smiles became broader. Whether there was a mention or two of familiar characters, or full character engagement, it was delightful. Although nothing is lost if you are unfamiliar with those characters.

The story was constantly filled with suspense. When I thought I finally had the mysteries solved, the story took another twist. Every twist was artfully created with perfect timing. The story was a constant source of fun and never felt too easy or too complicated. The author’s writing style is engaging and I couldn’t put it down. Simply, I loved it in every way.

It is helpful and recommended to have read Against All Odds before reading Into The Deep. It will make it even more enjoyable as some characters and stories are evolving from the first book in the series. While you’re at it, I recommend grabbing all of Brittney Sahin’s books. You’ll wish her characters weren’t fictional.

[Maya · Rating 5 out of 5]

Brittney Sahin is the queen of military suspense. I've read every single one of her books and it's been fun to watch her continue to evolve as an author. You won't be able to put this one down!

Into the Deep is the second book in the Delta Shielf Security series. We met the characters in book one but you do NOT need to have read the first book to enjoy this one. Audrey is a single mom whose (second) husband was killed in action. She's trying to make a new life for herself by relocating near her ex-husband when her house is broken into. From there, the life she thought she knew begins to quickly unravel.

Alejandro/Alex is her brother's best friend and is brought in to assist Audrey and her family in figuring out what is going on. He's got some demons of his own.

You can trust that any Sahin book is going to have you guessing at what happens next, with everything fitting together in a logical way at the end. I've given up trying to predict things and am just along for the ride! Plus, she's got fantastic metaphors and just such an interesting writing style. I can hear the conversations in my head because she writes internal monologue the way we all do it.

Sahin loves cameos/Easter eggs, which are so fun as a reader! My only quibble, and it's a small one, is that this book felt like it went overboard. Every single series got tied in some how and it felt overwhelming to me, someone who has read every single book at least once, so I suspect it's even more overwhelming for someone new to the author. While you don't need to have read the first book in the series, I DO think you'll get more out of this one if you read some of Stealth Ops: Bravo Team first (book one is Finding His Mark).

I can't wait for book 3! I just know Reed is going to wind up being my favorite of the series!

This was the best New Year’s Eve gift anyone has ever gotten me!! Thank you Brittney! 😘

Into the Deep is the second book in the new Delta Shield Security series by the one and only talented Brittney Sahin. If you have the time to read the first book in the series, Against All Odds, I highly recommend you do so before you read this book. That was you are somewhat up to date on what has happened already and are familiar with some of the characters. For those who are fans of Brittney’s and have read all her books up until this one, you are in for a treat. This book will give you all the feels and make your crossover loving heart extremely happy. 😍

Into the Deep is a romantic suspense story that will have you reading into the dark hours of the night and blowing your mind at the twists, tricks, and revelations that occur. My jaw dropped at least twice in this book and I mentally applauded Brittney for the mastermind that she is. The love story between Alejandro “Alex” Rodriguez and Audrey Langston is one that restores your belief in true love and the saying that goes, “love heals all wounds.” These two haven’t had it easy in the love department and they were reluctant in finding love again, but when you know you know. 😉

There is so much I want to say, but don’t want to spoil anything. I will write an updated review once the book releases. Just trust me when I say, this book is phenomenal and you need to pre-order it ASAP!! I don’t know how Brittney is able to do it, but each book she writes gets better and better. So go ahead and one click this book and add it to your Goodreads shelf because on February 24th, be ready to dive in to the world of Delta Shield Security!

[Charity E. Beaudoin · Rating 5 out of 5]

Into the Deep can have so many meanings and is such an appropriate title for this book. Brittney Sahin is masterful at creating stories not only with great characters, plots and surprises, but she is also able to reach the reader on an emotional level with her writing that keeps you invested and coming back for more.

After the death of her second husband, Audrey and her son Chase move to Colorado to be closer to Chase's father, Trevor, who is an overprotective ex-SEAL. She’s done with love, done with relationships, done with men. When her home is invaded, and she is attacked, it appears that it wasn’t a random break-in. Trevor calls in her newfound brother, Ryder, and his Delta Shield team to help investigate and protect Audrey and Chase.

Alejandro (Alex) is still recovering from his ex-wife’s betrayal, a betrayal that almost cost him his life. He wonders if he will ever be able to love and trust another woman again. Then he meets Audrey, during Christmas at Ryder's house, and he feels an instant attraction to her, but she is off limits, not only because she is Ryder's sister but also because he is not sure he can open his heart to another woman.

This is a love story with slow-burning romance, suspense and plot twists that you don't see coming. The banter between the characters, the camaraderie and love they have for each other can be felt. Brittney also brings in familiar faces from the other books/series in her universe to lend an assist, and I love to see characters used outside their own series.

I cannot wait for book 3. I think Reed's book is going to have the best banter and humour out of the three books!!!

[Jami Hoke · Rating 5 out of 5]

This is the latest released by the wonderful Brittney Sahin. Every time I read one of her books I think it’s the best one yet, but then she releases a new one and somehow it tops the previous one. She somehow manages to get better and better with every book, which says a lot about her talent! This is the 2nd title in her Delta Shield Security. Though it could be stand alone, you won’t be disappointed if you read Against All Odds first. It gives quite a bit of backstory on the main character Alejandro (Alex). She tends to do quite a few character crossovers which every reader seems to enjoy, I definitely know I do. Alex shows up to help protect Audrey who happens to be the biological half sister of his best friend/chosen brother Ryder (Against All Odds). Audrey was attacked in her home and ends up staying with her ex husband, once SEAL/growly alpha, father of her child whom she remained friends with. He made the decision to call Ryder and sends Alex ahead of him to help out. Audrey soon ends up down the rabbit hole of deception wondering what she can believe. Despite the chaos in her life the sparks fly between her and Alex as they determine what to believe and who they can trust. The spicy scenes, were slightly mild compared to some of her previous writing however, I was not disappointed in the least by this. The entire book was very well written and sucked me in until the very end. I have read all of her books at least twice and listened to the audiobooks. I definitely recommend this and all of her books!

[Hirali · Rating 5 out of 5]

Audrey and Alejandro, have sparks flying since their first meeting. Will they act on it though? He is her brother’s best friend, she is the little sister his best mate just found out about. The complications soup does not end there, she has a kid whose father is like her good friend and her second husband died in combat. When trouble comes knocking at her door Alex is willing to do anything to keep her safe.

This book is beautiful in a sense of how it develops and treads carefully of the topics that arise. There is so much happening at all times that even if I think I know how it may play out, Brittney has got another surprise for us. Delta Security is a gem, the fun banter and camaraderie is so nice to read about in a team. Chase, my man was so strong for his parents. I love when there are little characters that are so good and help lively it up during the worsts of times.

Brittney does it again! I am not sure how she keeps her universe straight but I am in awe of how amazing it is to get to read her writing. This book was outstanding and it started the year off with a great start! There is humor, depth, angst and oh so much more.

Reading this book made me feel like I was in a marvel movie, but with Brittney’s characters. I love it when she has brings people back who are help with the mission at hand. However, I get just as excited about all the new characters she introduces. I have my wheels spinning on what is coming 👀

[Amanda Grace · Rating 5 out of 5]

Into the Deep is the kind of romantic suspense that pulls you in fast and keeps the tension high. Brittney Sahin delivers a tightly layered story where the action never lets up and the stakes continue to rise.

Audrey and Alejandro are both shaped by betrayal and loss, and I really liked how that history informs their dynamic. The brother’s best friend setup and the not-so-fake relationship work especially well here, adding emotional weight without slowing the pace. Their connection builds in small, high-pressure moments, shaped by trust and the reality of what they’re facing together.

The plot is a tangled web in the best way. Twists hit when you least expect them, and while the action often takes center stage, the romance never gets lost. There’s heat simmering beneath the surface, woven naturally into the story without overpowering the suspense or the stakes.

The tie-ins to Sahin’s larger universe are always a standout for me. Seeing familiar faces from Stealth Ops and Falcon Falls Security, among others, felt seamless, and the new characters introduced here have me very excited for what’s coming next.

If you love romantic suspense with high-octane action and layered character work, this one delivers. Into the Deep is a strong, satisfying addition to the Delta Shield series.

Thank you so much to Brittney for this ARC.

Oh my, another fabulous one from Brittney. Book 2 of the Delta Shield Security series sucked me in almost immediately and I didn't want to stop reading. Alejandro and Audrey's story have quite the twists in it. Definitely didn't see some of them coming. Alejandro isn't the only one who can work some magic as we get to see Brittney work her own magic in his story. He is determined to be the good guy and not interfere with his best friend's sister's life, but the pull these two have cannot be ignored. Despite the circumstance that brought them together or the storm they find themselves in the middle of, the calm they bring each other is unmatched and is visible to all around them.
I absolutely loved all the in-person cameos of some of our favorites from her other series but the little nuggets of inside jokes or the one liners relating to her other series was my favorite and kept me smiling until the end. Also, never hurts to have Carter Dominick come up. He is one of my top Brittney heroes. I think I may have met my favorite heroine in Audrey's bff though. That girl is the female version of Carter and I was absolutely here for it.

[Layne Morrill · Rating 5 out of 5]

I'd give this 100 stars!! As always, I think her books can't get any better, then she goes and writes an amazing story!

Love seeing some of my faves return (Carter, Wyatt and Natasha, Gwen) in her stories, im never ready to say goodbye to amy of them.

Alex is a complicated guy... hes had it rough in the love department between his dad and his ex-wife... but he hit gold with his chosen family (Ryder and Reed)... they have each other's 6 any day, any time! He's content as he is with his chosen brothers... until he meets a long lost sister of Ryder and now she is in danger...

Audrey is ready to give up on love, just be happy with her son and her ex husband who she is great friends with... until her current husband died in a plane crash overseas and left key items in her possession that apparently hold the dark truths that shouldn't be let into the light... ever.

Holy roller coaster! I love how you think you know how the story goes, then all the sudden you turn the page and get a 18o flip and you're back to square one in figuring out who's behind what and why! Page Turner for sure!

Thanks for another excellent read, Brittney!!

[Kimberly Holmgren · Rating 5 out of 5]

Another exceptional story! Alex and Audrey are perfection! Alex has the world’s worst ex. His team is his brothers and that’s where he’s happiest, until the Christmas he learns his best friend has a sister. He’s taken by her from the moment he meets her. She’s a widowed single mom. Shes off-limits but it doesn’t stop him from thinking about her. Months later, she finds herself in trouble. Her husband may still be alive and he’s put a target on her back. Her newly found brother isn’t going to let anything happen to her. Alex is tasked to get to her fast and keep her safe until the team can get answers. Things spiral quickly, the danger and the feelings. They’ve both vowed that they are done with relationships but now they’re wondering if there might just be a happily ever after for them. Alex is a swoony, protective alpha from the start. These storylines go so deep that I always find myself guessing and failing at figuring out where it’s leading! I have no idea how she does it book after book but her stories suck you in and leave you beyond happy!

Thrilling, suspenseful, emotional – a perfect story

Audrey Langston needs help, and who better to get it from than her newly discovered brother and his team of Delta’s. Alex Rodriguez, her brother’s best friend and teammate, has spent the last few months trying to resist Audrey and her son. As they get to know each other through the threats and danger and the betrayals they’ve suffered in the past, they find a connection that can’t be ignored.

Brittney Sahin’s latest novel, Into the Deep, is a thrilling ride of action, a suspenseful hold-your-breath story full of twists and turns, and a journey of emotions that will bring you (as the reader) through a myriad of feelings like betrayal, mistrust, loyalty, ride-or-die friendship, and love. But most of all, it’s the story that keeps you riveted to the pages from beginning to end. She’s a master storyteller who keeps me captivated with details, twists and turns, and lots and lots of glorious emotion. I can’t get enough… and I can’t wait for Reed’s story!

[Andrea Smierciak · Rating 5 out of 5]

Into the Deep is the second book in the Delta Shield Security series. It can be read as a stand alone but recommend reading Against the Odds to get more insight into characters and past actions. The queen of military suspense has done it again. When you realize that Brittney Sahin has created another masterfully written book with many plot twists that will capture you from page one.

Audrey Langston has sworn off men and love after so many lies and betrayals. She moved to Colorado to start a new life with her son and to be near her son's father. Alejandro "Alex" Rodriquez is part of Delta Shield with his best friends and has also sworn off women after multiple betrayals from his ex.

These two fight the instant chemistry and their pull as there are many hurdles in their lives. Audrey is attacked in her home and is sent to stay at her ex-husbands lodge with her son. While the police, Delta Shield and her ex-husband try to determine if it's a random attack the pull between Alex and Audrey heats up.

These two must navigate enemies from all directions and determine where the threats are coming from. Throw in ex-wives, dead husbands and shadow Elite operator groups, you will not want to stop reading.

[Diana Wilson · Rating 5 out of 5]

Alejandro and Audrey are meant for each other. Each of them has had an ex tear their believe in love and trust apart.

Alejandro works with Audrey’s new found brother Ryder and she is off limits as far as he’s concerned but that doesn’t quench the feelings he has for her from the first time he meets her. She feels them too.

Her house is broken into and her ex husband and father of her child saves her just in time. He then calls her brother and his team comes to help him protect her and get to the bottom of why someone would want to break into her house and try to kidnap her.

This book is number two in the Delta series and it doesn’t disappoint. I’m so glad she brought back some of my favorites from past series. The Echo Team and what chaos would be complete without Carter Dominick. Greyson Chandler even makes an appearance along with my favorite badass woman Sidney Archer.

Great book and great series!

[Amanda S · Rating 5 out of 5]

I received Into the Deep early in exchange for an honest review.

Into the Deep by Brittney Sahin is the second installment of her Delta Shield series. If you're familiar with Sahin's work, it's no surprise that this story is interconnected with a few of her other series. Into the Deep follows Alex (Alejandro) and Audrey - and when she is already questioning who in her life is real/who can be trusted, she gets hit with even more uncertainty. Audrey is a mom & widow, who goes into hiding after her home is broken into. Alex is a divorced Delta operator who is adamant he will never fall in love after the betrayal by his ex wife. But did going into hiding play right into the "bad guys" hands? This second book is packed with twists and turns, suspense, and drama. Although my review shows 5 stars, 4.5 would probably be more accurate - If you are not familiar with Brittney's Stealth Ops or Falcon Falls series, this book may be confusing for you during certain parts.

[Reading is escaping reality · Rating 5 out of 5]

Wow. Talk about going in deep and completely wrecking me. I am absolutely obsessed with Brittney’s books and this new series hits the mark in every way. It hooked me from the very beginning and made me want to go back and enjoy a full reread of her other series all over again.

The twists and turns kept me completely invested, the spicy heated moments had me blushing, and the cute phrases had my heart swooning and racing. The tension between them and a piano was absolutely staggering. I truly did not want their story to end.

I cannot wait to see what happens in the next book in this series. This one left me desperate for more.

Loved this moment:

“Please don’t say my name like that.” I covered her hand, her warmth grounding me more than the bandage ever could. “Please don’t say that name at all.”

“Why not?” Her mouth pinched tight, etched into a sad line that hurt me to see. “Because I like how it sounds too much,” I confessed.

[Brandy · Rating 5 out of 5]

If you’re a Brittney Sahin fan, Into the Deep will not disappoint. I LOVED this book. It is highly recommended to read the 1st book in the series but can be read without reading book 1first. A lot of twists and turns to this story that kept me turning the pages wanting to know what happens next. Alejandro and Audrey have immediate chemistry when they meet and a past that is twisted together even though neither one of them knows this until Audrey is pulled into the middle of a government cover up and a dead husband (maybe not dead) who maybe a traitor to the US. Alejandro has an ex-wife who tried to kill him once and maybe involved in trying to help a traitor take down the secret teams who work for the government. Both Alejandro and Audrey have many reasons to not trust and not want to fall in love but sometime fate has other plans. I highly recommend reading Into the Deep…I am a forever fan of Brittney’s books.

[Jennifer Kincaid · Rating 5 out of 5]

Another ⭐️⭐️⭐️⭐️⭐️ read for me!! I absolutely love Alejandro and Audrey’s story!! Brittney is the best in military suspense books in my opinion!! Her missions are detailed and so believable they just draw you in for more and make you wonder what will happen next. I loved the emotional connection Alex and Audrey developed and how real their relationship felt of course there was some spice added in but I felt like this one was more about their attraction to each other not only physically but emotionally too. It always amazes me how Brittney weaves characters from her other stories into the action perfectly. This book does have a lot of past characters but also some news ones I can’t wait to learn more about!! This book can be read as a stand alone but it is book 2 in the Delta Shield Series and I think it just adds to the depth of the story if you read the first book Against All Odds first.

My goodness! Another 5⭐️ read from Brittney Sahin and I am not surprised!

Alejandro and Audrey had me hooked from the start! I loved their instant connection and how he interacted with Audrey’s son, Chase. I can definitely understand why she was quickly falling for him. The lies and deception were thick in this book but Alejandro definitely showed her that he was one to be trusted.

I also overly love when we get to see characters from other books come in. It makes me feel like we are just carrying on the story rather than in another series all together.

This book grabs you at the beginning and keeps you in a chokehold with your head spinning! Just when you think there couldn’t possibly be more, another bomb drops. 🤯

I am excited to see what is next for Delta Shield and I am definitely intrigued and want more of Aubrey’s best friend, Hollis, so I hope she is here to stay! We will see!!

Another masterpiece from Britney. Into the Deep finally gives us Alejandro and Audrey’s story, and after Ryder’s book, I had been counting down the days for this one. I loved seeing so many familiar faces return, especially watching Ryder learn what it truly means to be a brother to Audrey.

This story delivered all the twists and turns I’ve come to expect from Britney—just when I think I’ve figured things out, she finds a way to surprise me in the best possible way. Audrey’s growth throughout the book was beautifully done, and I especially loved seeing her develop trust and understanding as the story unfolded.

Without giving anything away, I am beyond excited to see what the Delta Team brings us next. Reed and Hollis already have me eagerly awaiting the next book, and I may even have a guess about who’s going to keep Gwen on her toes!

Riveting. I think that's the key word to describe the new Delta Shield Security book. I was locked into Alejandro and Audrey's story from the very first page and didn't want to stop reading for a second. The intense chemistry between Alex and Audrey has been apparent from the moment they met just a few months earlier, however, both have sworn off falling in love ever again due to two of, quite possibly, the worst ex's ever. Add in that she's his best friend's sister... With their undeniable attraction, delicious banter, twist after crazy twist, and a few cameos from some of our beloved Teams family, and Alejandro and Audrey delivered a heart-stopping story I didn't want to put down until I got to the very end.

"I was ready to deliver my soul on a platinum platter for her. Let her etch her name into my heart, too. This was different. This was... This is how it's supposed to be, isn't it?"

Another incredible story by Brittney Sahin! We get Alejandro and Audrey’s story in this one. They are both so damaged by prior relationships, determined to stay closed off to future love, but their pull toward each other is something neither can deny. There is nonstop action as the mystery of who is after Audrey and why unfolds delivering multiple twists and turns along the way. We get to fall in love not only with the main characters but also with Chase, Audrey’s brave and awesome little boy, and Hollis, her unexpected best friend (who I really hope becomes a star of her own book soon). And of course, in true Brittney fashion, Delta Shield is not alone on this mission. They are helped along the way by many of our favorites from other teams, some in big ways like Gwen and Natasha providing cyber support. Truly a great addition to this series and Brittney’s library!

If you like a storyline that is full of mystery, twists, and turns that keep you guessing. If you like two hurt souls finding their way back. If you like random humour and nail-biting scenes, then this book is for you.

It has everything you crave. I couldn't put this one down. It had me gasping out loud with the twists, my heart beating faster with the anticipation in some ooo la la hot moments.

There was so much going on in this one with how they found their information, and it amazes me every time how authentic Brittney is with writing these pages.

I also loved seeing other teams from previous series come through. It makes me want to go back and do a reread for the hundredth time lol

Im looking forward to the next in this series. They just keep getting better.

I loved it! Brittney always writes an incredible story that makes the characters feel real. I love having characters from past series make little cameos because it let's you "see" what they are up to, even if its only snippets.

With this story, I loved the connection between Audrey and Alex. After everything Beth put him through, I am glad that he found Audrey. Not that Trevor didn't treat her right, but they both found their 'meant to be' person in each other. I also loved how great of a relationship she still has with her ex-husband, because not everyone can have that. I'm hoping to see Trevor get his HEA one day as well. Now, to wait for Reed's story...

5⭐️ Into The Deep is the second book in the Delta Shield Security series and is such an excellent read! Alex and Audrey are both divorced and each carry a heavy load of heartache and turmoil. When Audrey’s house is broken into, Alex and his team, along with her ex-husband Trevor, and a whole host of other characters prepare to protect her and her son Chase while they find the truth behind the secrets and lies from her deceased husband Mitch.
This story is so action packed, angsty, and healing all rolled into an epic story for Alex and Audrey.

Everytime Brittney comes out with a new book. I sit back and wonder if she could possibly do better than the last book. Well, Im going to stop asking that question because she honestly does!! Alex and Audrey were fantastic together. This book was absolutely fantastic and the storyline was phenomenal. It flowed so smoothly and the intrigue keeps you turning the pages. Just when you think you have it figured out a new twist pops up. It was a great ride and the ending was perfect!! Added bonus having alot of old friends stop by. Definitely five stars!! Fantastic job as always!!
