Brief intro: Henry Cooley has good friends and a good life. He’s secure in his job and his relationship. He and Tom, the love of his life, are about to celebrate their twenty-first anniversary as a couple. Their son, CJ, is in his second year at Cal Arts. Henry's only problems are his growing dissatisfaction with his job and the fact that Tom's parents still hate him, even after all these years. At least those are his only problems until the morning he wakes up to discover Tom has vanished.
Review: Most of it are flashbacks, but the story is just amazing. Beware: Cliffhanger ahead, but it could have just ended like this.
