Merlin's Bones

Set in post-Arthurian England, this story follows 10-year-old Amby, who possesses second-sight and discovers a powerful, unoccupied castle. As ancient and modern forces, including legendary figures like Mordred and Morgan le Fay, vie for control of a reality-altering machine, Amby and Dr. Elaine Brusen become embroiled in a centuries-spanning struggle across worlds. Fred Saberhagen masterfully reimagines Arthurian legend with a mix of adventure, romance, and danger.
