Swallowing Dark

Canaan thought he'd left a violent and dangerous past behind when he and his son arrived from Zimbabwe, until new case worker Martha decides to re-examine his refugee status and he's forced to fight for their lives for a second time. But when lives depend on it, is the truth always the best story to tell? As he opens up his past, Martha moves from trusting his word to suspecting him of lying and as this psychological thriller progresses she begins to confront terrible events happening in her own life--but are either of them who they seem, and is the truth ever a simple story?
