This may be a short book, but it packs a punch for sure. Bug is the sweetest main character, trying to solve the mystery behind Uncle Roderick staying behind as a ghost. Not only is this a book about ghosts, it is also a book about grief, about finding your identity, and of course, about the transition to middle school. All of the characters in this were great, and the character arcs were well done. This will be a great book to put in any middle grade readers' hands.
