Larissa writes dark paranormal romance, erotic sci-fi/paranormal romance (under the name Sydney Croft), and contemporary romance. The contemporaries and dark paranormals so far have had a medical element, which she just loves. Larissa writes because she loves to read and has since she was very young. She has always been a voracious reader with an active imagination, and created her own worlds in her head which she then decided to get out on paper. She wrote her first full-length novel at the age of 13.
Larissa and Stephanie Tyler co-wrote several paranormal fiction books together. Larissa used the pen name Sydney Croft. The publisher requested that they did it since they were both unknowns, having no track record, no books published. They were asked to come up with a single name rather than using two. So they threw some ideas back and forth, and then settled on Sydney (from Alias's Sydney Bristow,) and Croft (from Lara Croft, Tomb Raider.) They don't even have their real names in the bio in the back of the books!
