John Kloepfer is the author of the popular Monsters Unleashed and Zombie Chasers series, as well as the out-of-this-world alien trilogy Galaxy's Most Wanted. He lives in Los Angeles with his wife, Jenny, and their dog, Doozy.
Mark Oliver likes being an illustrator because he gets to paint, draw, and use his creative genius in many different ways using a computer. Sometimes he does it so well, he wins awards for it (the Stockport Children's Book Award in 2006 and 2011, among others).
Mark's very clever, but he never brags about how clever he is, just in case people ask him tricky questions about zombies, string theory, or moral relativism. Visit him at www.olly.net.
