Jim is a full-time SF&F writer, scientist and laser geek (Ph.D. Electrical Engineering, specialty laser physics), and former running-dog-lackey for the bourgeois capitalist establishment. He's been writing for over 30 years, with 15 published books. His first success came through self-publishing when his books went word-of-mouth viral, and sold enough that he was able to quit his day-job, start working for himself and write full time--his new boss is a real jerk. That led to contracts with traditional publishers like Open Road Media and Harper Collins Voyager, and his books are now a mix of traditional and self-published.

The four novels in his new hard science fiction series, The Blacksword Regiment, were released in July 2020.  Right now he’s fleshing out ideas for the next book in The Dead Among Us, he’s writing another episode in The Treasons Cycle, and he’s working on a new fantasy series The Deck of Chaos.

Jim was born in Seattle, but he's lived most of his life in California, though he did live on the east coast and in Europe for a while. He now resides in Arizona with his wife Karen and three little beings who claim to be cats: Tilda, Julia and Natasha. But Jim is certain they're really extra-terrestrial aliens in disguise.
