Bec feels herself drawn to the dead Bill-E, and as her spirit seeps into his corpse, she finds herself capable of restoring the body's functions... Bill-E draws a breath... and so does Bec...the first free breath after sixteen hundred years of imprisonment in a remote cave. As she occupies Bill-E's body, it changes to become like Bec's original body. Bec discovers that she has the ability to absorb memories from anyone she touches, a skill that will help her in her quest to destroy demons.

With Beranabus, Grubbs, and Kernel off exploring for clues about the Shadow behind the demon invasion, Bec is left behind with Dervish. But with his health in decline, Lord Loss knows Bec is the most vulnerable piece of the Kah-Gash, a Demon hunting group. As hoards of demons, werewolves, and zombies advance, Bec needs to figure how to reach Beranabus with crucial information about the Shadow. Will she be able to contact him in time?

Demons from previous books that were killed and properly disposed of are coming back to life and new demons are introduced in this fast paced horror thriller. Bloody and exciting, Death's Shadow carries on the tradition of the earlier Demonata books. Darren Shan, who never expected to become a children's writer, has done it again.
