The Shadowmancer series is a collection of fantasy novels written by GP Taylor and includes Shadowmancer, Wormwood, Tersias and The Shadowmancer Returns.

The story starts in the english village of Whitby and tells the tale of superstition magic and witchs. The series has recieved some controversy over it's negative portrayal of witches and pagans and is seen as a Christian allegory in the same vein as CS Lewis' The Chronicles of Narnia. GP Taylor is considered to have started writing the series to counteract what he saw as a rise in new atheism propaganda messages in children's books.
