There’s no way she can make up for the damage she caused, but she has to try.

Whitney Daley risked everything in an attempt to right her wrongs, but just when she thinks she's finally free she's abducted by one of the men whose life was forever altered by the drug she created. There's no way she can convince him that her participation in the project wasn't what he thinks, which means she's nothing but his helpless little captive.

When he gets his hands on the mystery woman who claimed to have intel on the man responsible for turning him into a monster, there is not a chance in Hell that Blade is going to let her get away. Whatever it takes to get answers so he and his team can finally get their revenge, he's prepared to do, and an angelic face, wispy blonde hair, and the largest pair of baby blues aren't going to change that.

Until he learns the full truth about Whitney's involvement in the creation of the drug, that changes everything.

If you love romantic suspense that keeps you flipping pages way later than you planned, Sinful Revenge is definitely one to add to your reading list.

From the beginning, the story pulls you right in. There’s an underlying tension that runs through the entire book, and it creates that “just one more chapter” feeling that makes it really hard to put down. Jane Blythe does a great job balancing the suspense with the emotional side of the story, so you’re not just following the action—you’re also getting invested in the characters and what they’re going through.

One of the things I liked most was how real the characters felt. They both have complicated pasts and baggage they’re working through, which makes their connection feel more genuine. Watching their relationship develop while everything else is unfolding around them adds a lot of depth to the story.

The suspense elements keep the story moving, but they never completely overshadow the romance. Instead, they raise the stakes and make those quieter moments between the characters feel even more meaningful.

Overall, Sinful Revenge is a solid mix of suspense, emotion, and romance. If you enjoy stories where the characters have to fight through some serious obstacles before finding their way forward, this one is definitely worth checking out.

Another unstoppable, action packed book in this amazing series by Jane Blythe. This book just flows from the previous book and it continues to have your heart pumping furiously. Blade and Whitney go on a massive journey to find the elusive Dr. Gardner and to keep Whitney safe while Blade is still trying to piece together the connection between Whitney and Dr. Gardner and when he does it is quite the revelation. Everything about this book will have you gasping especially Blade and his team when their ruthless determination to find Dr. Gardner seems to be their sole purpose in life and anyone and anything that gets in their way is collateral damage until their humanity rises to the surface once again. I am absolutely loving this series and the characters are all so strong and have only one goal in mind and that is to be “normal” once again but along the way they find their other half. I keep saying amazing about this series because that is definitely what Jane Blythe delivers each and every time.

This series keeps getting more interesting with each book. The Delta team is still desperate to get to the scientist who is the architect of their experiments. When they find Whitney running from the scene of an explosion that nearly cost the lives of their teammates, Blade is determined to find and interrogate her.

This book starts right after a literal bang, then keeps you hooked until you turn the last page. Blade is dealing with a lot of demons, so when he captures Whitney, he doesn’t hold back on what he thinks she deserves. His attraction to her is the only thing that prevents him from taking out all his frustrations on her. What makes this story stand out is the real connection that Whitney has to these conditions. And boy is that a doozy I didn’t see coming. Whitney has a lot of demons of her own to work through, and when they finally start communicating, their connection leaps off the page. Blade and Whitney’s story is a must-read and a great next installment in this wild series.

I absolutely loved Whitney. She was a very smart girl, I mean off the charts kind of smart. Even better though...she has a big heart. When trying to let Delta Team know some information that she thought would be useful turned out to be much more than that. She doesn't have the best luck when it comes to meeting the team again. It wasn't the best way to meet them again that's for sure.

With Blade trying to get answers from her, he actually learns more about himself in the process. I loved the chemistry between these two and seeing them both grow as individuals was a very heart warming process. The team is growing stronger than they were even as a team full of guys. You add strong women that help complete some of the men of Delta Team and you definitely have a lot more reasons than even before to get answers.

Blade and Whitney’s story is emotional, eye opening and action packed. All Whitney wanted was to help people and her work was turned into something she didn’t recognize anymore, she needed a plan to get away. She never wanted to hurt anyone, but Delta team doesn’t know that and Blade is after her to get to the truth no matter what has to be done. Whitney isn’t what he thought she’d be and listening to her explain herself and the remorse she felt for what happened to them and what she had done to them and everything that the doctor has put her through at such a young age. Maybe she isn’t the villain in this story after all. So many emotions, feelings that Blade thought he’d never feel again, will the doctor ever be caught or will they continue to chase after him or will they realize that love is so much more than revenge?

Blade—and honestly, the whole team—could use a lesson in listening before jumping to conclusions. His mistake stings, but what makes it compelling is that he can’t stay away from Whitney, no matter how hard he tries. His roaring alpha-protector side is always close to the surface, even as he attempts (and fails) to hide his own vulnerabilities from her.

Whitney is both fragile and incredibly strong, a combination that makes you admire and root for her fiercely. Your heart aches for the pain and torment of her childhood, making her courage in the present even more powerful. Together, Blade and Whitney sizzle with a connection built not just on heat, but on shared vulnerability and healing.

The team’s loyalty, sharp banter, and unshakable brotherhood continue to anchor the story, adding strength and depth to every high and low.

Sinful Revenge by Jane Blythe is another fantastic addition to this brilliant series. This time we get Blade and Whitney’s story, and as always with books from the talented Jane Blythe, readers are taken on a rollercoaster of excitement, tension, and emotion.

Whitney is a wonderful heroine- highly intelligent yet still carrying a vulnerability that makes her incredibly relatable. Blade, on the other hand, is driven by a deep need for revenge, and at times his desperate search for closure pushes him to set human emotions aside. This contrast between them makes their journey all the more compelling.

Watching this couple navigate their struggles and move toward their well-deserved HEA is an absolute pleasure. As always, Jane Blythe delivers a gripping, emotional read. I’m already eagerly looking forward to the next book in the series.

I'm absolutely loving the suspense in this series and how the story follows on.

This was about Whitney a chemist who had been held for years, she escapes and falls into the hands of the men she helped drug for years before, and especially Blade.

The dynamic between Whitney and the guys was fantastic. They all had their issues but the protectiveness they display despite everything I just love.

But Blade and Whitney were perfect. Mister big and tough with little miss innocent. She learnt fast but I enjoyed how Blade was with her. She needed his type of care.

Suspense, danger, and loaded with family dynamics and drama, with a great steamy romance. These two were just the best.

So well written and totally engaging, I couldn't help but get involved. Loved it!!

This third story featuring Blade and Whitney is full of ongoing action, suspense and intrigue, revenge and mistrust balanced beautifully with emotion, character growth and found family. Whitney had my heart with her vulnerability and painful reminders of what she thinks is her fault to bear. Blade’s need for revenge is palpable and fearsome but in the end his emotional growth from his past and perceptions provides redemption. The overarching plotline progresses wonderfully as evil is slowly being unraveled by the Team and the strong women added. For me this was a can’t put it down until the end read and I look forward to more in this riveting series.

Wow both Blade and Whitney had a horrible past. Whitney being a genius graduated college at the age of ten then her parents sold her. Her creation that was created for good only caused harm. Blade and his team are out for vengeance even if its to go after Whitney to get to the doctor that put them through h*ll. What follows is something that Blade and his teammates never saw coming. Now if Whitney can only forgive them and herself. I loved Whitney and Blade, what a fantastic couple. I am loving this series. It is definitely intense and highly emotional. I highly recommend this book and series.

Jane Blythe has done it again! Blade and Whitney exploded off the pages in this story! I love the “found family” that is Delta Team and how DNA does not make a family whole. I appreciated Whitney wanting to do something to try to get closure for the guys, but since this is only Book 3 in the series it hurt my heart to see her go through her situation. But, as always, HEA is guaranteed and I feel both Blade and Whitney will continue to grow closer. Can’t wait to learn more about the rest of the guys!

I'm really enjoying this team of unique guys, modified by illegal medical intervention.
Whitney is a genius, sold to a scientist at only 10yrs old and kept until her escape at 22. She created the medicine that has altered these guys lives and they want her to suffer.
Is she really the villain in this story or a victim as well? This story was action packed and brought out emotions in these guys especially Blade.
I really loved their chemistry and life discoveries from both of them.
What a great read this was and I can't wait for book #4.

After reading the first two books in the series I was super interested to learn more about Whitney and Blade. They do not disappoint.

Their chemistry was unexpected. He captures her and she’s under his thumb. She has information he needs. He’ll do whatever he has to to get it. They have such a heated exchange. I never knew what would happen next. I love a story that keeps me on my toes. There’s action and adventure but also those cozy moments that warm your heart.

I can’t wait to see what happens next!

Sinful Revenge

OMG! What a fantastic and very intense story. This story is about Blade and Whitney. Whitney's story was truly horrific. Her parents are truly despicable. Whitney survived twelve years with a maniacal doctor who thought he was God. He definitely knows how to live off the grid and the team are certainly having a difficult time finding him. The ending of this book was definitely the most intense of the story. The team definitely got to Whitney in the nick of time. So glad that Whitney survived her ordeal. FANTASTIC job Jane! I would highly recommend this book!

Book 3 in this brilliant series carried right on from book 2. Blade was so determined to get his revenge that made it hard to for him to coos in anything else. Whitney was just amazing! I really loved her, her intelligence and also emotional maturity made her so special.

Blade did redeem himself and proved that he was loyal and faithful to the core.

An exciting and thrilling book, full of excitement and this amazing team I love! Roll on the next book I can’t wait!

Blade and Whitney's story was dangerous, heartbreaking, surprising, and scary. I felt so sorry for Whitney, the way she grew up not having anyone that cared for her or no friends. Blade was so focused on his revenge, that he didn't think before he acted. What he did to her was unforgiving. Highly recommend,can't wait to read the next one in the series.

Another fantastic action packed read from Jane. I love Jane's female characters as they really come into their own throughout their story's and the boys learn so much about themselves. Whitney is quirky and smart and I loved her from the get go....and Blade's arc is fantastic. A great read....this series is awesome.

Book three in this fantastic installment focuses on the girl who gave the tip. Finding her gives new insight and what they thought they knew was once again uprooted. Action packed with a bit of a kink, age gap and virgin.

Blade and Whitney shouldn't make sense as a couple but they are made for each other. I am enjoying this series even if it's a little darker. Lots of emotions and action. The characters are complex and the storyline engaging.

Whitney blew up the lab that she thought was empty to escape Dr. Gardner. Blade chased Whitney through the forest and captured her. Blade torchered her till he realized she was telling the truth. Whitney's parents sold her to the doctor at age 10. Loved this story.

I’m not sure I could fall in love with a guy that did what Blade did to Whitney but to each his own.

Since she was ten years old she’s had no freedom to call her own. She invented the serum that changed Delta Teams lives but not to hurt but to heal.

Evil will always find a way to use good for evil.

This team is way darker than we’ve seen before. It’s a change from the norm that’s for sure.

This is the third book in the series and honestly the stories are becoming more completing.

This time we have Blade and Whitney. Now he has many reasons to be suspicious of her and when he catches up with her it's not pretty. But pretty soon some if her secrets are revealed and his understanding of her involvement with there enemy takes a very different perspective. As they return to the Deltas mansion the sparks between them become undeniable. But there plan to learn more about the enemy doesn't quite go as planned.
I enjoyed the dynamics between the could and thought Whitneys forgiveness of Blade's actions came rather easily though this was understandable in her need for connection and friends.
Another great book from Jane Blythe!

Holy smokes!!! Blade and Whitney are intense. From the beginning of the book to the end I could barely put it down. The chemistry of these two characters are strong. The fight that they have to go through to finally get eachother is inspiring.
