Elizabeth Nettleton is an author and editor currently based in Oxfordshire, England. An avid reader and writer since childhood, she was once so engrossed in her book that she ran into a lamppost.
There is nothing Elizabeth loves more than magic and getting lost in other worlds (except for her family, friends, and pets, of course!), so she primarily writes fantasy, sci-fi, and horror. When she's not reading or writing, you can find her playing with her kids, daydreaming, or trying not to die in a video game.
