Fifteen-year-old Miya never expected her spring break to end with a last-minute trip to Avalon. But when she finds her favorite tree hollowed out overnight, she and her best friend Kyle are drawn into a world most can only dream about.
Fascinated by Arthurian legends, Miya's obsession turns to dread when she realizes Avalon's covered in a thick layer of ice. And that's not the worst of it. Nimue, the Lady of the Lake, informs her that most of King Arthur's court has fallen under a silencing spell--including Merlin, the great wizard.
With Kyle stuck taking Arthur's place, it's up to Miya to find the Holy Grail. But finding the elusive goblet will be nearly impossible once Miya realizes she has to die in order to retrieve it.
