Karen has lived on both the Atlantic and Pacific coasts, but prefers to reside in the Green Country of Northeastern Oklahoma, where she grew up. She enjoys the changing seasons in Tulsa, where she lives with her photographer husband and their floppy-eared schnauzer, A.J.

An avid reader from an early age, she wrote stories as a child and began seriously pursuing a career in publishing in 1981. A writing class convinced her that writing a novel wasn't as easy as it looked, but she finished her first manuscript in a few months and began work on another...and then another. Her first book was published by Dell in 1984, and after writing eight novels under the pseudonym of Karen Whittenburg, she became a Harlequin American Romance author and began publishing as Karen Toller Whittenburg in 1987.

Karen credits her love of daydreaming as the catalyst for her life as a writer. She is currently at work on her next novel.
