When a billionaire's daughter goes missing, it's all hands on deck.

Missing kids isn't one of Ryan Wolfgang's usual cases. "Wolf" is the head of Arrow Tactical Security, a black ops firm that takes on dangerous missions. His life is fast-paced and that's the way he likes it.

But is she a runaway or a kidnapping victim?

Alexandria Rolfe has grown up in the shadow of her father—the world-renowned forensic scientist and psychologist, Dr. Richard Rolfe. She's determined to build her own reputation now that she's graduated with her PhD, so when she gets the call about the missing teenager, she jumps at the chance to prove herself.

Will they find her alive?

Ryan wants to help his old classmate and maintain his perfect recovery record. Alexandria wants to bring the girl who refers to her as Aunt Alex home, but she can't deny the career boost from the contacts alone. When they decide to team up, they both hope for a rescue, but they might just find more than they were looking for . . .
