Comes the Dark Stranger (The Martin Shane Novels Book 1)

Martin Shane is searching for someone to kill, though he doesn't yet know who. Eight years prior, Shane and five fellow soldiers were captured in Korea and tortured by a sadistic Chinese colonel. One of them broke under torture, revealing information in exchange for his own life. Before Shane could identify the traitor, shrapnel damaged his brain and erased his memories. After years in a mental institution, a chance event restores Shane's mind. Uncertain of what happened to him, he returns to the town where the soldiers enlisted together, determined to uncover the truth and seek revenge—regardless of what he must destroy in the process, including his understanding of the war, his fellow soldiers, and himself. The novel explores one man's fractured psyche as he confronts the collision of past and present.
