Doc Mortis (Invisible Fiends)

The fourth thrilling book in this darkly funny, horror series Darren Shan called "deliciously nightmarish". Kyle wakes up in hospital - which is strange, because he doesn't remember being ill. And that's not all. He's also deliriously flitting in and out of the Darkest Corners, and in the shadow version of the hospital the surfaces aren't clean, and the sharp instruments aren't used for healing. It's Kyle's most terrifying experience yet, and it's about to get much, much worse. The doctor will see him now . . . .
