FEARLESS: An Option Zero Novel

Option Zero #6

by Christy Reece

Will her darkest hour be his last chance for redemption?

Having pushed the horror of his past down to the deepest part of his soul, Sean Donavan had forced himself to become someone else. Someone who had no heart, no soul, and little humanity. He devoted himself to his profession, existing within the limited confines of a man with no purpose other than survival. Then one spring day, a young woman bumped into him and his entire world changed. His bitter, ice-coated heart melted and for the first time in years, he allowed himself to feel. Happiness as he’d never imagined existed for him and he was at peace.

After surviving her own devastating loss, Serena never believed she would find love again. When she met Sean, she knew in an instant that her prayers had been answered. She fell in love and married her hero, expecting a long, beautiful life ahead. She saw the courageous, kindhearted man beneath Sean’s mask of pain and sorrow. The life they were building was exactly what she’d dreamed of having with him.

And then it all came tumbling down.

In the midst of heartache, evil attacked. Like a runaway locomotive, Sean’s past came roaring toward him, taking out everything within its path. He never anticipated that Serena would be caught in the aftermath. Now she’s been taken, and it’ll take every ounce of their fortitude and faith in each other to withstand the hell they face.

True love has no limits and courage knows no boundaries. Fighting for what one believes in is part of humanity, but fighting for the love of your life means you’re willing to give your all. This time, Sean knows that the possibility is all too real and he’ll gladly give up everything for the woman who is his very heartbeat.

This is Serena and Sean’s story and it does not disappoint,just like all the Option Zero books.Each book is somehow better and more mysterious than the ones before it. The Wren group is still after the Oz family,still stalking from the shadows,looking to dominate everyone and everything and Colton Kingsley may be one of the worst yet. Sean and Serena will go to any lengths to save the other and to get as much information to dismantle this organization as possible. If you enjoy a lot of twists,turns and surprises and heart this book is for you. Everytime I think I know who is at the top of Project Wren I am wrong through another twist or turn. I cannot wait to see who Lazarus really is and how he finally is brought down.Sean and Serena’s love is put to the test over and over but true love,faith and family are the glue that holds it all together,and family isn’t jus the one you are born into but also the one you find and create through love and respect.

I have been looking forward to Sean and Serena’s book and it does not disappoint. The Wren Group is still after OZ, and this time they may have bitten off more than they can chew. Colton Kingsley is looking to make a name for himself so he can move up the ranks, and he knows that Serena Donovan may just be his ticket to the top. Colton Kingsley is evil to his core, there really isn’t another word for him. He tries to get Serena to see that helping Wren Group is good, but she has other plans.

Through all the twists and turns, the love story between Sean and Serena pulls at your heart strings. Their love story unequivocally shows us that they belong together, even though they have hit a rough patch the trust they have in one another may just get them through this fight. I have loved this entire series, but Fearless may be the best one yet! Serena and Sean’s story was everything I was hoping and so much more.

Received ARC from author for honest review.

What a freaking rollercoaster of emotions this book evoked in me. Goodness, I remember thinking to myself (WHY WOULD SHE DO THIS TO THESE PEOPLE?) but I just couldn't put it down. I read from cover to cover in 1 day because I HAD to know why and who and WHY. I love that about Christy's writing, her brain is a scary place. While this book was darker than most of her stories, you are not disappointed and I think she takes it right to the edge of what you can handle then brings you right back. The past has a weird way of coming back to wreak havoc, and that was for sure the case for Sean and Sabrina. Lawless is next, and there are large expectations and I can't wait to see what happens next.

[Kelly Mcclure · Rating 5 out of 5]

This is the one you've been waiting for...THE love story of all love stories. Sean and Serena seemed like the most lovable couple and how could anything keep them apart.? Only the vilest of creatures would even be able to try. I always enjoy delving in to the minds of these narcissistic sociopaths. And the Wren project is apparently home base for most of them. I am so ready to have the next one appear and finally get the answers that we Option Zero fans are waiting for. Catch up if you haven't read the earlier books in the series. It's just a knock out.

Christy Reece has done it again! “Fearless” is everything I love about the Option Zero series-heart pounding suspense, deep emotional connections, unforgettable characters and a love worth fighting for. Sean and Serena’s story pulls at your heartstrings while keeping you on the edge of your seat. The emotional depth of their relationship, the challenges they face, and the courage it takes to fight for each other makes this such a compelling.

Fearless is a beautiful reminder that even when life brings unimaginable pain, love, hope and courage can give is the strength to keep fighting.

[Susan · Rating 5 out of 5]

Serena and Sean's story was wonderful! Serena is ever so smart and empathetic; this book showcases her courage as well. Sean, as we all know, has some trauma in his background and we find out what it is, what has sent him away from friends and family. The bad guy is truly awful and deserves much worse than he got. Some fabulous interactions with familiar characters, and a couple of new introductions as well. Hank is a delight! Another fantastic addition to the Option Zero series.

I was gifted a copy of this book to read in order to give an honest review. I’ve been a Christy Reece fan for many years and have been anxiously awaiting Sean’s story. To get the in-depth experience for this book you will want to read the series. Sean and Serena’s story has twists and turns that leave you begging for more and screaming WHAT all at the same time.

[Kristin · Rating 5 out of 5]

Sean & Serena’s book has been a long time coming and did not disappoint. Sean finally faces his demons and Serena is pivotal for gaining more information about WREN, the shadow organization that OZ has been after for several books. Fearless has everything: action, suspense, a horribly evil villain, and a heartwarming reunion for Sean & Serena. Can’t wait for the next!

[Randi Simpson · Rating 5 out of 5]

I couldn't put this one down!! Christy Reece takes you through all the emotions in the most unexpected ways!! Each book in the series is better than the last and I can't wait for the next one to be released.

[Terri Brunner · Rating 5 out of 5]

I know I say this on every book Christy writes but it’s another amazing book! I just can’t get enough of her books. I have no idea how these 2 characters found each other but you will not be able to put this book down! If you haven’t read the whole series PLEASE do so. You will not be disappointed!

[Diane Saul · Rating 4 out of 5]

This is part of a series but could be read as a stand alone. It is full us suspense, plenty of drama and romance. Sean will do anything to protect Serena. I thoroughly enjoyed this book from the first page to the last. I would not hesitTE TO REDCOMEND THIS BOOK.

FEARLESS
AN OPTION ZERO NOVEL Christy Reece
The Option Zero series is a series that holds you spell bound in each book and Fearless definitely doesn’t disappoint! Sean and Serena each have faced heartache, when they found each other healing was happening till
it wasn’t. Can the OZ team come to their rescue and fight the evil that is stalking them? Can they have a happy ending? If you want an intense filled adventure then this is definitely it.

[Sammye · Rating 4 out of 5]

This is the sixth book in the Option Zero series. Sean and Serena had an idyllic marriage until his past came back to haunt him. Serena was targeted and he would stop at nothing to protect her. This is a fast paced, action packed story filled with drama, suspense, love and devotion. I enjoyed every page!

[Kristen Johnson · Rating 4 out of 5]

Christy Reece has done it again, masterfully pulling me right into the story and holding me hostage til the end. Fearless, like its fellow Option Zero books delivers the perfect blend of romance and suspense.

Fearless is a tale of two souls finding each other after so much heartache. Their path together is full of twists and turns but they make it through to the other side. I love how the story is woven together and how both Sean and Serena work together.

[Alima Livzletlivz · Rating 4.5 out of 5]

The problem with darkness was that it never really went away. You have to endure it, face it, accept it, learn from it and then hopefully, you could move on ~~ Christy Reace, Fearless

Serena Donovan - He was a romance hero come to life. He saw beneath the surface of the slightly geeky, sometime too serious-minded woman. She fell in love with him on that first date.

Sean Donovan - His heart went into overdrive. Serena was everything he’d ever dreamed of having in a life partner. And he had ruined it.

Christy Reece gave us a glimpse of Sean and Serena at the end of “Reckless”, and that Serena was able to track the love of her life. Their story takes off in “Fearless”

A love that starts with a promise of happiness, embarks on a journey of pain, devastating loss and resilience. Christy Reece lets us feel how much is at stake before she takes it away. Sean’s story is one of the most heartbreaking stories that Christy Reece has written, and she writes it with such care and tenderness - I broke into tears!

Sean and Serena both come to the fight with scars, and neither pretends they don't hurt. But when the past comes roaring back with a vengeance, their fight, courage and sacrifice is nothing short of fearless!

Christy Reece has always been a genius with her villains and Colton Kingsley takes the cake so far. When Colton collides with Serena and Sean is when the extraordinary story of their love, unwavering faith, and their single and resolute goal to save innocents risking their lives is a testament of their courage and bravery.

And the OZ team breathes and lives that choice. A family of flawed, fiercely loyal people and bound by a shared purpose, they are warriors working to help the innocent, the abused, and the missing. And when one of their own is in trouble, all bets are off and the whole team shows up, including the resources lurking in the dark.

The long waited story of Serena and Sean is indeed a story of “Fearless” warriors and the missing pieces of the puzzle seem to be slowly falling into place. Another brilliant story from Christy Reece and her OZ warriors!

Received an advance review copy for free, and I am leaving this review voluntarily.

I was so excited to open up this book and see that Sean and Serena are the main characters. I am a big fan of all of Christy Reece’s romantic suspense stories and characters, but I knew these characters and plot would be something very special. Sean and Serena are strong and caring heroes who always put other people before themselves.

Before Sean and Serena even meet, they each experience their own very traumatic incident that causes them to give up on love, happiness and life. Fortunately, they meet each other, and that is when their lives happily change. They immediately fall madly in love each other and discover that they have found their perfect soulmate!

Both Sean and Serena work for Option Zero (OT). OT’S latest case is to concentrate their time on completely destroying the Wren group. That is known to be the most “diabolically evil” group. They also plan to kill their leader, Colton Kingsley. Kingsley is an evil monster who has no soul, heart, or feelings.

In fact Christy Reece admits that this is the “darkest emotional book” she has ever written. I have to admit that, when either Sean, Serena or both, found themselves guests of Kingsley, for the first time, I was so scared, that I wanted to close my eyes - as if that were possible!

On the other hand, Ms. Reece, in another note, calls this book “the most uplifting story. she has ever written. I agree, because Sean and Serena are two people who survived very dangerous situations, returned home as heroes, and were still as happy about their life, and as madly in love with each other as they first met.

Another winner for Christy Reece!

[Lynn · Rating 3.5 out of 5]

Sean and Serena Donovan had been separated for years before Sean finally decides to let Serena go so that she can find happiness with another man. Before the divorce papers can be filed, Sean is taken by WREN. Serena doesn't know this until she is also captured and bargains for her husband's life by working with WREN, all the while, gathering Intel for OZ. While they are apart, Sean realizes all the mistakes he has made in their marriage and vows to get Serena back so they can try again.

There is very little romance in Fearless since Serena is captured for most of the book. However, Serena's bravery and intelligence are on full display as she remains at the WREN compound. There are lots of inner monologues filled with angst and regret, but after a while they become repetitious. Many of the characters from previous Option Zero novels are a part of the story, and some of their loose ends are tied up, but from the beginning, the romance feels short changed. In addition, very little new information about WREN is revealed. Overall, Fearless starts with great promise, but leaves so much opportunity on the table.

[SOMDReigel · Rating 5 out of 5]

The action and mystery continues in the Option Zero series with the focus on estranged couple Sean and Serena. This is a very emotional read with suspense, redemption, reconciliation, forgiveness, and a horrid villain that only Christy Reece can write. One of the many things I loved about this story is that Serena’s faith shines through and is woven throughout the storyline. As soon as I opened this book, I was drawn in and the pages kept turning. This is what I always get from a Christy Reece book. Highly recommend as well as everything written by this author.
Note: This is a complete story but all in the books in this series are a continuation from the beginning. I recommend starting at book 1, Merciless. The story will continue in book 7.

[Sheri Morell · Rating 5 out of 5]

This book has all the feels, I loved reading Sean and Serena's story. What they went through with Kingsley shows what kind of evil is in the world. This book had me on the edge of my seat and I couldn't put the book down. My favorite part was how they set Kingsley up at the end. Also loved what Serena did for Sean at the end. Thank you Chrisy for another fantastic read. I love catching up with the OZ family

[Linda · Rating 5 out of 5]

Christy Reece has done it again. While Sean and Serena’s story was a long time coming, this book had all the feels and kept me up way past my bedtime. There are plenty of twists and turns and we are inching closer and closer to finding out who is behind Wren. New baddies are introduced and I still haven’t gotten over the loss of one character. I can’t wait for the next one in the series and I’m hoping it’s a particular character’s book.
