What is the creature referred to as a "hybrid author?" Are they beings spliced together genetically or perhaps some liger-jumbling-of-authors?
Those answers are very imaginative, to be sure, but it's actually quite simple. A hybrid author is an author that has published through or is publishing through traditional and Indie paths.
Elana Johnson, young adult author of the Possession series published by Simon and Schuster (part of the Big 6 - er - 5 - or whatever it is now). She is about to release a new book, titled ELEVATED, on February 18th. This book is one she is self-publishing. So she falls under the definition of hybrid author.
Susan Kaye Quinn is another great example of a hybrid author. She first published with Omnific Publishing but has since made her mark in the sci-fi world with her breakout Mindjack novels and future-noir Debt Collector serial. She's not one to let genre be a stumbling block either. She's also published a Bollypunk thrill-read and a middle grade fantasy.
Indie Romance Convention's 2014 Mistress of Ceremony, Victoria Vane, is also a hybrid author. She's an award winning author who pens smart and sexy romance from historical to contemporary. Her Devil Devere series is self-published under her Vane Publishing LLC. And get ready for some Hot Cowboy Nights as Victoria also has a new series releasing from Sourcebooks, the first book being SLOW HAND, set to release November 2014.
When you take a look around, you'll find plenty of other examples, some that may have been around for quite a while. "Hybrid author" is just a term, a way to reference, to categorize. The authors, themselves, are just authors, plain and simple. They're storytellers embracing the traditional and Indie paths. We, the readers, just happen to be the benefactors. I, for one, am glad for it.
