I'm somewhat wondering about the reliability of the narrator-protagonist. Did his crush really interact with him as he describes or was this embellished by wishful thinking. That is - can I trust the author? Otherwise, the dialogues and considerations of playing the divorced parents off against each other, plus the mother's new husband and the circumstances of living under one roof, are plausible for a bright teen.

Starts well, moving between the young protagonist's feelings and events of present and past, the crisis between his parents and the appearance of a threatening stepfather, the origin of the boy's eating disorder that's left "to give it time..." A different set of circumstances than any book I've read in a long time (perhaps since Dickens in h.s.?), certainly more engaging than the A.B. Yehoshua I abandoned last week.
