"Kalo Taxidi" (have a safe journey) is a novel about two brothers who were separated in childhood. Part one concerns Brian, a neurosurgeon in training at the Johns Hopkins Hospital in the 1940's when neurosurgery was in its formative stages as a surgical specialty. Part two relates the experiences of Brian's brother Marshall from the time he was rescued as a child from a storm in the Agean Sea to his service as a British agent in Greece during World War II.
