From Amazon.com:
MJ lives in the foothills of the Sierra Mountains with his wife and two daughters. Due to a bizarre and horrific childhood incident at his school library, MJ never developed an interest in adult literature.
When not reading or writing books for kids, he runs a video arcade company building retro arcade machines just like he played as a child. MJ is available as both a court approved zombie expert and for intensive "zombie safety" school lectures
He just released his latest graphic novel, Zack & Zoey's Alien Apocalypse.
