His memory
was gone.
His instincts were not.

Alex Castle awakens from a coma with no memory, no history, and no explanation for the instincts that survived.

Unfamiliar places feel known. His body reacts to danger before his mind can name it. Then impossible flashes begin arriving ahead of reality, pulling him toward a truth waiting beyond the edge of memory.

Whatever happened to Alex is not over—and the closer he gets to who he was, the less certain he becomes that the past wants to be found.
