In a world with no power, no law, and no mercy-no one is safe.

Months after a catastrophic solar flare destroys the power grid, the residents of Michigan's remote Upper Peninsula grow more desperate by the day. At a crumbling lighthouse on the edge of Lake Superior, Lena and Shiloh Easton carve out a fragile refuge. But when a group of escaped convicts breaks in and steals Lena's insulin, Lena must track them down. Because if she runs out, she dies.

Sheriff Jackson Cross has sacrificed nearly everything to keep his people safe. Now another threat looms: Sykes-a violent fugitive with nothing to lose-and his fellow convicts are loose in the woods, and the bodies are piling up. Not everyone will survive what's coming.

Eli Pope has found a second chance-at life, maybe even love. With everything to lose, he's fought hard to become a better man. But with Sykes and his men circling like wolves, Eli has one mission: protect Shiloh and Lena. No matter what it costs. Even if it means becoming the man he swore he'd never be again.
