Blood Beast

Blood Beast is the fifth book in Darren Shan's The Demonata series and was released 4th June 2007. It is narrated by Grubbs Grady, the narrator of Lord Loss and Slawter. The plot is part of a two part story, along with book six. Though the previous four books have not been in chronological order, this book is the furthest book into the future. It mainly deals with whether or not Grubbs Grady will be struck with lycanthropy and how he will deal with this problem.

The title was originally announced at the Edinburgh Book Festival, and Darren Shan read a small sequence about a demon attack on a plane, which featured Lord Loss.
