Starred Review From the provocative titles and the unusual narrative voices to the juxtaposition of fact and wit, Wait! What? (2 titles) is not your typical biography series. Paige and Turner, a pair of siblings, act as joint narrators, holding an extended conversation about a famous person. Smart, curious, and competitive, each narrator enjoys nothing more than topping the other's cool factoid or amusing anecdote with an even more amazing one. And while readers will enjoy the narrators' one-upmanship, it doesn't slow the pace of the biography, which offers chronological accounts of the people profiled, noting their strengths and occasional flaws, clearing up misconceptions, and providing insights into their personalities. Each title gives Paige and Turner an opportunity to debate the question posed in the title. In Albert Einstein Was a Dope?, Turner points out Einstein's spotty performance as a student, while Paige counters that he "revolutionized science." In addition to the tiny heads that indicate whether Turner or Page is speaking, at least one black-and-white, digital illustration appears on nearly every page, giving the books an inviting look. Combining Dan Gutman's ongoing interest in biography with his talent for humor, this engaging new series for young readers is a winner.
