Sebastian Stuart had a heady childhood. His brilliant, acerbic mother was the Entertainment Editor of Life magazine, and his father was an Oscar-nominated filmmaker. James Baldwin was a dinner guest and Bette Midler paid a courtesy call. Yet beneath the glittering parties, the family was haunted by unspoken tragedy.

By age fifteen Sebastian was dropping acid and turning tricks for money. He found friendship and solace with his cousin Tina, an aspiring poet and striking beauty who was signed by the Ford modeling agency. When Tina began to exhibit symptoms of schizophrenia, Sebastian was torn between a desire to save her and the fear of losing himself in her madness.

From San Francisco in the '70s to New York in the AIDS-ravaged '80s, Stuart's quest for self-discovery leads to a sad and shocking understanding of his family history and the price of grief denied. And, ultimately, it leads to redemption. By turns hilarious, irreverent and heartbreaking, What Wasn't I Thinking? is an unflinching evocation of loss and forgiveness.
