It’s been months since Cassidy Shaw has heard from her mother, Rosa, a world-renown scientist. When she does, it’s in the form of an urgent edict to retrieve a key. Arriving at Rosa’s apartment in Cincinnati, Cassidy encounters strangers. One man who seems determined to silence her. The other, could he be her savior? Luke Dixon enters the fray, believing his neighbor is being attacked. Never one to ignore someone in distress, he’s then shocked to realize he’s the one needing rescue. Bound together through violence, Cassidy and Luke must come to trust each other as they embark on a search, armed only with the key and Rosa’s cryptic directions. It’s a journey with unexpected answers and decades-old research. A search with more questions…and a lethal enemy who returns when least expected.

Foiled from gathering the data Rosa had sent her to retrieve, Cassidy worries what to do next. The scientific files are lost in the sewers of NYC, but new directions arrive. Now, Cassidy is asked to collect intel that’s in Texas, locked in the archives of the man Rosa was once married to. Wounded by the lies from the only person who’d ever been her family, Cassidy carries on. Despite her confusion of her past and those she can trust, Luke has more than proven he’s reliable. There’s no doubt in Luke’s mind that he’s sticking with Cassidy for the answers to Project Xol. Besides his need to protect her, he struggles to ignore why he’s so determined to remain with her when trouble is nipping at their heels. Danger follows them once again, both from Rosa’s home to Luke’s past in prison. Getting to Texas is one matter, but obtaining the files they need is another, especially when their enemies won’t hesitate to kill. Lost is the second book of the Project Xol series, which continues in Find.

Armed with data they don’t know what to do with, Cassidy and Luke struggle to escape the invincible recruits from Project Xol. Desperate for help, Cassidy strives to locate a safe place for Luke to recover. There’s no time to fall into a false sense of security—not when she’s wanted for alleged murder. She needs to protect her father’s intel from zealous scientists and to figure out a way to avoid the law. Trust doesn’t come easily for Luke, but he must have faith in Cassidy when he’s too wounded to protect her. Even though they have limited options on the run, he hopes they’ve found an unexpected ally in a rural location. Too high of hopes, it seems, because they’re only pushed closer to law. Captured, Luke reaches out to his brother for help. But could that one call be all it takes for the leader of Project Xol to finish him? Find is the third book of the Project Series, which continues in Stolen.

After another narrow escape, Cassidy hopes for a break—for any kind of a breather from constantly being on the run. She and Luke head to a safe house arranged for them by Zero, and it’s there that they find new sources of potential help. Hendrick’s journal might show a promise of where to locate the elusive scientist, but it more than digs up Cassidy’s past. Finally given a chance to recover from his injuries, Luke struggles to accept this temporary relaxed state. After all, how much longer can he and Cassidy deny their intense chemistry? Peace doesn’t last, though, as a newcomer trespasses on the property. Together, they head to Mexico in pursuit of the man who might have answers to Project Xol’s new agenda. Getting there is a challenge, but running into the cartel is a bigger dilemma… Stolen is the fourth book of the Project Xol series and it continues in Reclaim.

Reunited with one of the Project’s original researchers held captive at a cartel compound, Cassidy is tasked with delivering answers about a so-called miracle drug. She struggles with the fear of being separated from Luke, anticipating he’ll be harmed unless she cooperates. The details the cartel wants aren’t forthcoming, and instead, she’s instructed to find another Project colleague in another city. Luke doesn’t sit still once he’s parted from Cassidy. The danger in this jungle is unlike any peril he faced in prison or on the streets, but using his head—and ignoring the ache in his heart at losing what he’s sure is love—he plans an escape. Once they’re on their way, however, he still lacks the chance to tell Cassidy how much she means to him. They leave behind death and horror to find a scientist in the city. Wrought with doubt and confronted with hostility, they realize they have the key pieces to ending Project Xol. Faced with the responsibility of destroying the resources that could save many lives, decisions are harder to make. And when it becomes clear Cassidy is expected to be reunited with her family, the stakes are higher than ever. Reclaim is the fifth book in the Project Xol series, which continues in Given.

Taken to a Xol lab, Cassidy prepares to meet the one woman who’s never wanted her. It’s not clear why the scientist requires her now, but she hangs on to two hopes—that Luke has gotten away and is safe, and that the vial of genetic material they’d fought to protect is destroyed. Life isn’t fair, but she pushes aside the cruelty of losing Luke so soon after finding his love. Survival, however it may come, is imperative, because she refuses to fail in ending the diabolical “cure.” Stranded in Mexico, Luke must contact the one person he’s always wanted to keep from danger. It doesn’t take much to convince his brother to be his backup in rescuing Cassidy from Project Xol’s team, and soon, the brothers follow her trail. Even with the help of the billionaire who’d once funded the research, it seems impossible to take down such a corrupt team hellbent on unethical experiments and producing something that can change the world forever. Despite the odds against them, they can only fight until the end, hoping they have made it in time… Given is the final book of the Project Xol series.
