LAWN BOY

After his grandmother gives him an old riding lawnmower for his summer birthday, this comedy’s 12-year-old narrator putt-putts into a series of increasingly complex and economically advantageous adventures. As each lawn job begets another, one client—persuasive day-trader Arnold Howell—barters market investing and dubious local business connections. Our naïve entrepreneur thus unwittingly acquires stock in an Internet start-up and a coffin company; a capable landscaping staff of 15 and the sponsorship of a hulking boxer named Joseph Powdermilk. There’s a semi-climactic scuffle with some bad guys bent on appropriating the lawn business, but Joey Pow easily dispatches them. If there’s tension here, it derives from the unremitting good news: While the reader may worry that Arnold’s a rip-off artist, Joey Pow will blow his fight, or (at the very least) the parents will go ballistic once clued in—all ends refreshingly well. The most complicated parts of this breezy affair are the chapter titles, which seem lifted from an officious, tenure-track academician’s economics text. Capital! (Fiction. 9-12)
