Spies in Canaan by Park David

Michael has travelled a long way from his boyhood under the endless skies of the Midwest. His retirement is peaceful, if solitary. But one day there is a visitation: a mysterious car on the seafront, and a package delivered. From its contents, Michael understands that he has been commissioned to undertake a final journey. As Michael makes his way deep into a distant desert – a strange and liminal landscape that lies between hell and redemption – he undertakes another journey, into long-suppressed memories: of Vietnam and the dying days of war, and to face a final accounting for what was done.
