Publisher's Synopsis
Tyler and Aidan face the repercussions of exposing the cracks in the high-tech system that runs their city, but that's not their only problem. News of a break-out in the tombs brings the unlikely couple to a new level of fear. Aidan's vindictive twin Adam has some unfinished business, and he's not about to let them get in his way. Terrified of what he might be planning and what his actions could mean for them and their home, Aidan and Tyler must find a way to get to Adam before he can complete his tasks, or face the consequences.
