A boy recounts his adolescent angst during a summer helping his father train racehorses; in PW 's words, ``Graham's soul-searching is neatly counterbalanced by snappy dialogue and the sheer excitement of horse racing.'' Ages 12-up. (Mar.) Green by nature , blue from gloom--this downcast amphibian searches (while his slothful sister snoozes) for Felix's Hat (Four Winds).
