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 several bestselling series, including the #1 New York Times bestselling urban fantasy of Kate Daniels, the rustic fantasy of The Edge, paranormal romance of Hidden Legacy, and Innkeeper Chronicles, which they post as a free weekly serial.

Ilona Andrews's books are praised for being guaranteed good reads, often noted as one of the brightest voices in urban fantasy.
