Karen Marie Moning is an American author renowned for her paranormal romance and urban fantasy novels. Born on November 1, 1964 in Cincinnati, Ohio, USA, she graduated from Purdue University with a Bachelor's degree in Society and Law. Prior to becoming a full-time writer, Moning worked as a bartender, computer consultant, and insurance specialist.

She initiated her writing career with paranormal romance novels set in Scotland but later transitioned to urban fantasy, inspired by her growing interest in Celtic mythology. This shift led her to focus on the Tuatha de Danann, or Fae—an ancient race of immortal beings living secretly among humans. Relocating her settings to Dublin, Ireland, she created the internationally bestselling urban fantasy Fever series.

Moning's novels have been highly successful, featuring prominently on The New York Times Best Seller list, with some reaching the number one position on multiple national lists. She is a recipient of the prestigious Romance Writers of America RITA award for Best Paranormal Romance and is a multiple RITA nominee.

Her books have been published in twenty-four languages, attracting fans worldwide. Despite a brief marriage to Neil Dover, she currently divides her time between the mountains of Georgia and the beaches of Florida.
