Blood of Amber (The Chronicles of Amber, 7)

Blood of Amber is the seventh book of The Chronicles of Amber; an epic fantasy series written by six-time Hugo Award winning and three-time Nebula Award winning author, Roger Zelazny.
The ten books that make up the series are told in two story arcs: The Corwin Cycle and the Merlin Cycle.

Pursued by a fiendish enemy, Merle must battle through an intricate web of vengeance and murder that threatens more than the San Francisco Bay area. For Merle Corey of California is also Merlin, son of Corwin, vanished Prince of Amber; and the forces, seeking to destroy the royal house, have unleashed sorceries that can strike anywhere, especially at the very heart of Amber.
