Thea Harrison is the pen name of American author Teddy Harrison, who has made a significant mark in the literary world with her engaging works. She is best known for her contributions to the genres of paranormal romance, sci-fi fantasy, and contemporary romance. Among her most celebrated works is the New York Times and USA Today bestselling Elder Races series. Harrison's talent for storytelling is not confined to just one pseudonym; she has also penned contemporary romance novels for Harlequin Mills & Boon under the pen name Amanda Carpenter.

Harrison embarked on her writing journey at a young age. She wrote her first book, a romance, when she was just nineteen years old, and went on to have sixteen romances published under the name Amanda Carpenter. Her passion for writing coincides with a lifelong love of books — a passion so intense that she taught herself to read when she was four years old. Recounting this early love for reading, Harrison humorously notes that this was around the time she attempted to ride her tricycle to work, not knowing where it was but certain it had to be interesting if people went there every day.

Residing in Colorado, Harrison has not only built a career around her love for books but also adores animals, living with two small dogs that boast very large personalities. She holds a couple of graduate degrees and has collected a grown child along her life's journey. Currently, she is working on various new projects across sci-fi fantasy, paranormal, and contemporary romance, continuously expanding her repertoire and enchanting readers worldwide.
