Benjamin Harper lives in Los Angeles where he edits superhero books for a living. When he's not at work, he writes; watches monster movies; and hangs out with his cats Marjorie and Jerry, a betta fish named Toby, and a tank full of four rough-skinned newts. He tends a bog garden full of carnivorous plants and also grows milkweed to help save Monarch butterflies. His other books include the Bug Girl series, Obsessed With Star Wars, Rolling with BB-8, Hansel & Gretel & Zombies, and many more. Alex Lopez is from Sabadell, Spain. He became a professional illustrator and comic-book artist in 2001, but he's been drawing ever since he can remember. Lopez's pieces have been published in many countries, including the United States, United Kingdom, Spain, France, Italy, Belgium, and Turkey. He's also worked on a variety of projects from illustrated books to video games to marketing pieces.
