The Necromancer (Book Four, The Secrets of the Immortal Flamel)

Dee is now is being chased by his former 'comrades' for failing one too many times. Perenelle, with the help of the Elder Areop-Enap, my favorite of he Elder race--a fifty foot arachnid with a human head--has managed to defeat the Sphinx and escape Alcatraz, leaving Machiavelli and Billy the Kid stranded upon the island.
