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.
