"The summer I was eight years old, five hours disappeared from my life"?so runs the catchy opening to Heim's impressive first novel. The speaker is Brian Lackey, now a troubled teenager, once an introverted kid growing up scared in the small town of Hutchinson, Kans. The reason for his memory lapse and his fear, as we and Brian learn during the course of the novel, turns out not to be the space aliens that he first suspects, but his molestation at the hands of his Little League coach. The key to Brian's reclamation of those lost hours is homosexual hustler Neil McCormick?the slugger on that Little League team and an accomplice to Brian's sexual abuse. Working its way over the course of a decade toward Brian and Neil's reunion, the narrative unfolds through chapters whose points of view alternate among Brian, Neil and a handful of their siblings and confidants. Heim makes numerous freshman mistakes, including a relatively static narrative, prominent characters who outlive their usefulness and occasional lapses in the writing. He also creates scenes of genuine beauty, however, and handles his complicated characters and delicate subject matter with calm assurance.
