Former soldier Ryan Granger’s life has become all about numbers: 13 months since he was shot in the head 7 months spent in a coma 6 months since he woke, a changed man 5 hours since he’d been kidnapped 4 minutes since he’d opened his eyes in an underground cavern 3 minutes since he’d heard a woman calling for help… Two strangers trapped together. One impossible way out. And zero chance his team isn’t ripping the world apart to find him.
