Kelly kicks off his Ballpark Mysteries series of early readers by introducing cousins and budding sleuths Mike Walsh and Kate Hopkins, who are trying to figure out who has stolen the lucky bat of a star Boston Red Sox player. While few readers will doubt whether Mike and Kate will save the day, Kelly throws in plenty of behind-the-scenes Fenway Park trivia (both in the story and in an appendix) and keeps the story moving at a quick pace, which should easily hold baseball-lovers' attention. Meyers contributes b&w artwork not seen by PW. Also available: The Pinstriped Ghost. Ages 6-9. (Feb.)
