[Tunes for a Small Harmonica] is laced with eccentric characters and a slick narrative style that made me laugh out loud. It's a good, amusing read but I felt that Ms. Wersba's central character was somewhat strangled by the author's sophisticated humour: I cared about what J. F. said and did, and not about the character herself. And the book's ending seemed too neat and contrived to be altogether convincing. Still …, this is splendid entertainment.
