When her past comes back to haunt her… Former FBI cyber security agent Eryn Calloway worked many cyber investigations during her career as an FBI agent and while serving as Blackwell Tactical's cyber expert. But when her computer is locked with ransomware, she suddenly finds herself facing the biggest investigation of all. Failure to solve the case and find the hacker could result in the loss of her very life. Can she let the one man who can protect her get close enough to do so? Enter former Green Beret, deputy Trey Sawyer who offers to serve as her bodyguard. Trey has been in love with Eryn for a year, but she lost her husband several years ago and isn't ready to open herself to the potential for pain again. She's kept Trey at arm's length and wants to do so now-after all, she can take care of herself. But she has a four-year-old daughter to protect, so Eryn reluctantly agrees to let Trey into her world. But when they're thrown together in a race for her life, she has to combat both a vicious enemy-and the pain from her past. Is Trey trustworthy enough to let him into every area of her life, or is the risk too great?
