Death is familiar territory to Sam. His mother died when he was a teenager. He was a father for all of two hours and eleven minutes. His wife committed suicide, and now his sister is missing—presumed dead. The only thing holding him back from the abyss is his father and Halo, a secret organization that helps relocate evolved ones, like Rox, on the run. But Sam is tired, and death seems like the only thing worth living for.
