However, unraveling the killer's intricate plot isn't her only problem. She has a cousin who is nowhere to be found. A dangerous hunter has escaped from prison. Ranger X is all but obsessed with his latest case, and she worries it's consuming him entirely. On top of all that, Lily must make a decision that will affect not only her own life but also the life of the man she loves more than anything else—and once that decision's made, there'll be no turning back.
