Vanishing Acts is one of the best books I have ever read. The mystery is complex and the characters' methods of solving it make you want to whap yourself on the forehead in an “of course!” manner. The way the authors entwine two ingenious mysteries into one book and don’t confuse the reader is amazing. The cases both are solved by two very smart kids. They make rather an odd couple, a cartoonist and an incredible detective, both great soccer players, exploring the mysteries of junior high together, possibly more than just friends. A great story, guaranteed to please all readers. Read!!!!!!!
