When his music career becomes stagnant, Theo Vilmos seeks solace in a secluded cabin in the woods where he discovers an old book written by his great-uncle that transports him into the terrifying world of Faerie.

More than thirty years have passed since the events of the Memory, Sorrow, and Thorn trilogy, and the world has reached a critical turning point once again. The realm is threatened by divisive forces, even as old allies are lost, and others are lured down darker paths. Perhaps most terrifying of all, the Norns--the long-vanquished elvish foe--are stirring once again, preparing to reclaim the mortal-ruled lands that once were theirs....

With King Olin imprisoned and Prince Kendrick slain, the royal twins Barrick and Briony have been forced to flee their homeland. But both families and nations can hide dark and terrible secrets, and even if Barrick and Briony survive learning the astonishing truths at the heart of their own family and of Southmarch itself, they must still find a way to reclaim their kingdom and rescue their home--from traitors, tyrants, a god-king, and even the angry...

"Takes place in the half-year after the end of To Green Angel Tower, and tells of the attempt by Isgrimnur and a force largely made up of Rimmersgard soldiers to destroy the remaining Norns as they flee back to their homeland and their mountain. It also answers some questions about what actually happened in the immediate aftermath of the fall of Green Angel Tower"--Goodreads.com.
