Pastor’s daughter Dee Henderson is a lifelong resident of Illinois, USA, and currently resides in Springfield. She believes that marketing books should be about the stories rather than the writer, so she keeps a low profile compared to many authors. Her background is in mathematics and computing science (B.Sc 1988) and she had a high paying job as an engineer before she moved into full-time writing in 1996. Her technical expertise has given her an unusually keen insight into the structural aspects of storytelling. The results are plain to see; since 1999, Dee has produced two bestselling fiction series - the acclaimed O'Malley series and Uncommon Heroes – as well as eleven stand-alone titles.

Dee’s books brilliantly mix suspense and romance, and her characters undergo varied and interesting faith journeys that are integrated skillfully into the storylines. Dee’s work has won or been nominated for several prestigious industry awards including the RWA's RITA Award, the Christy Award, the ECPA Gold Medallion, the Holt Medallion, the National Readers' Choice Award, and the Golden Quill.
