USA TODAY best-selling author M.A. Rothman is one of the most unlikely novelists you’ll ever meet. He’s an engineer first and foremost, with a background in the sciences, and somehow or another, this writing habit of his has turned into a bit more than just a run-of-the-mill hobby.

He primarily writes stories that focus on two things: technology and international intrigue. This writing tends to span the genres of science fiction, techno-thriller, and mainstream thrillers.

When not writing, he enjoys cooking, learning about new technology, travel, and spending time with his family.

D.J. (“Dave”) Butler grew up in swamps, deserts, and mountains. After messing around for years with the practice of law, he finally got serious and turned to his lifelong passion of storytelling. He now writes adventure stories for readers of all ages, plays guitar, and spends as much time as he can with his family. He is the author of City of the Saints, Rock Band Fights Evil, Space Eldritch, and Crecheling from Wordfire Press, and from Baen: Witchy Eye, Witchy Winter, Witchy Kingdom, and Serpent Daughter; The Cunning Man and The Jupiter Knife with coauthor Aaron Michael Ritchey; In the Palace of Shadow and Joy as well as Between Princesses and Other Jobs; Abbott in Darkness; and with M.A. Rothman, Time Trials.
