Ilona Andrews is the pseudonym for a husband-and-wife writing team. Ilona is a native-born Russian and Gordon is a former communications sergeant in the U.S. Army. Contrary to popular belief, Gordon was never an intelligence officer with a license to kill, and Ilona was never the mysterious Russian spy who seduced him. They met in college, in English Composition 101, where Ilona got a better grade. (Gordon is still sore about that.)

Gordon and Ilona currently reside in Oregon with their two children, three dogs and a cat. They have co-authored two series, the bestselling urban fantasy of Kate Daniels and romantic urban fantasy of The Edge.
