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.
