About the author

Award Winning, NY Times Best Selling Author

Delilah Devlin

Until recently, award-winning romance author Delilah Devlin lived in South Texas at the intersection of two dry creeks, surrounded by sexy cowboys in Wranglers. These days, she’s missing the wide-open skies and starry nights but loving her dark forest in Central Arkansas, with its eccentric characters and isolation—the better to feed her hungry muse! For Delilah, the greatest sin is driving between the lines, because it’s comfortable and safe. Her personal journey has taken her through one war and many countries, cultures, jobs, and relationships to bring her to the place where she is now—writing sexy adventures that hold more than a kernel of autobiography and often share a common thread of self-discovery and transformation. Delilah Devlin is a prolific and award-winning author of erotica and erotic romance with a rapidly expanding reputation for writing deliciously edgy stories with complex characters. Whether creating dark, erotically-charged paranormal worlds or richly descriptive historical stories that ring with authenticity, Delilah Devlin “pens in uncharted territory that will leave the readers breathless and hungering for more…” (Paranormal Reviews) Ms. Devlin has published over 140 erotic stories in multiple genres and lengths.
