ENTER THE PAST TENSE, by Roland Haas
Subtitled My Secret Life as a CIA Assassin, this chronicles the life of a first-generation American whose childhood was marked by vicious chronic bullying, parental indifference, and almost total non-communication. Brilliant but emotionally shut down, Haas was spotted by the CIA while in college. His contact "Phil", who often popped up out of nowhere, arranged Haas's improbable future as a covert agent. The resulting life was anything but boring. Even the complex explanations of various governmental agencies and situations was an eye-opener. It's a 3.5, worth reading if you are a devotee of spy stories.
