Green (Football Genius
) wades into John Feinstein territory with this fast-paced story about two middle-schoolers who put themselves in peril to probe steroid use on a youth baseball team. Josh LeBlanc's father is a pitcher who never made it to the big leagues. After he's cut from the farm team for the Toronto Blue Jays, he projects his unfulfilled dream on Josh, yanking him from the school baseball squad to play for the Titans, a travel team run by Rocky Valentine, a winning-is-everything caricature who supplements his income by selling milk additives that will reputedly help players bulk up. When Josh is also slipped some “gym candy,” he talks over his suspicions with school reporter Jaden, and together they investigate with exciting, if predictable, results. A subplot about a bully who thinks Josh is moving in on his girlfriend adds nothing, and Josh's mother is basically relegated to serving meals. But most kids will not notice, focused instead on the action-heavy, high-testosterone plot that has Josh in near-constant motion. Ages 8–12. (Apr.)
