P is for Real Pigeons Fight Crime by Andrew McDonald [author] and Ben Wood [illustrator].
This is a graphic novel with three parts – The Great Breadcrumb Mystery, The Bat Trapper, and Danger at the Food Truck Fair. In their first mystery, all the breadcrumbs have disappeared from the local park. Oh the horror! But don't worry, the pigeons are on the case! The second and third parts are related cases the pigeons are called to solve.
Other than reading comic books when I was in elementary school, this is the first graphic novel I've ever read. The pigeons all have different personalities. The stories and the illustrations are funny. I'm not really a graphic novel reader, but this book was quick and easy to read and a lot of fun.
