James Knapp was born in New Hampshire in 1970, and has lived in the New England area since that time. He developed a love of reading and writing early on, participating in young author competitions as early as grade school, but the later discovery of works by Frank Herbert and Isaac Asimov turned that love to an obsession.

He wrote continuously through high school, college and beyond, eventually breaking into the field with the publication of the Revivors trilogy (State of Decay, The Silent Army, and Element Zero). State of Decay was a Philip K. Dick award nominee, and won the 2010 Compton Crook Award. Ember, The Burn Zone, and Fallout were all written under the name James K. Decker.

He now lives in MA with his wife Kim.
