The epic adventure comes to a close ...

Kay's father is still missing--and worse, now nine-year-old Ell is too. More determined than ever, and with time running out as the twelve nights come to an end, Kay must puzzle out the riddles laid before her in this new land of Bithynia--and help restore the world to order--before her dad and sister are gone forever.

Andrew Zurcher concludes his sweeping and magical tale of imagination, adventure, and the transportive power of storytelling in a world as captivating as Lyra's Oxford and Alice's Wonderland.
