Sign of Chaos
Roger Zelazny
 Merlin realises that Wonderland, where he and Luke are trapped, is an LSD-induced hallucination made real by Luke's powers over shadow. As a Fire Angel (a vicious creature from Chaos) pursues them, he administers medicine to Luke. The Fire Angel is weakened in a fight with the Jabberwock and Merlin is able to finish it off with the vorpal sword. He leaves Luke to sober up. He seeks his stepbrother Mandor, who thinks that their half-brother Jurt may be trying to kill Merlin in order to take the throne of Chaos. Fiona contacts them, and they investigate a shadow-storm. Merlin and Mandor return to Amber, and then along with Jasra they wrest the Keep of the Four worlds from Jurt and the sorcerer, Mask. They learn that Jurt has (at least partially) turned himself into a living Trump, as Brand did, and that the sorcerer Mask is in fact Merlin's ex-girlfriend Julia.
