John Dee
The main story arc charts the adventures of fifteen-year-old American twins, named Sophie and Josh Newman, whose regular lives working at their summer jobs (Sophie works in a coffee shop, Josh in a bookstore) are turned upside down by the arrival of Dr. John Dee. Dr. Dee engages the bookstore owner, Nick Fleming, in a battle of magic in an attempt to steal an ancient book, "The Book of Abraham the Mage" (a.k.a. the Codex) from him. Dr. John Dee snatches the book from Josh's grasp, but Josh manages to retain two pages. Dr. John Dee also kidnaps Nick's wife Perry Fleming and imprisons her on Alcatraz Island.
