Dark Promise

Lara and Trevor flee Seattle in the wake of rising chaos. Demons converge on what's left of civilization, urging it to implode even faster.
Constantly hungry, besieged by dark forces, Lara and Trevor need every resource they've developed as a couple to keep from ripping each other apart. Neither of them trust Lara's half-baked magic, but it's all that stands between survival and certain death for them and their unborn child.
The remote location that was supposed to solve all their problems actually made them worse. Rash choices throw Trevor into a confrontation with his deepest fears, but he doesn't back down. Lara's life hangs in the balance, and he'll do anything to get her back. Anything.
