The Mysterious Benedict Society is a book of wits, teamwork, self discovery, and danger. One  day an ad is in the paper saying; ARE YOU A GIFTED CHILD LOOKING FOR SPECIAL OPPORTUNITIES? It then gives you an offer to take a test. In the end, only 4 orphans pass, Reynie, Sticky, Kate, and Constance. They go on a dangerous mission to save the world. It's a puzzle, and sometimes sad, but altogether it's amazing.
