The Terrible Two
Anything with pictures, and blurbed by Dav Pilkey and Jeff Kinney, is bound to be successful with middle grade readers, and this had enough humor to recommend it. Niles is an appealingly devious character who understands the necessity of stealth when pranking, and Miles is haplessly clueless but well meaning. The names are a bit goofy but not over the top, as are the situations. A must purchase title for middle school libraries.
