The House of Always

For fans of Brandon Sanderson and Patrick Rothfuss, The House of Always is the fourth epic fantasy in Jenn Lyons' Chorus of Dragons series that began with The Ruin of Kings.
What if you were imprisoned for all eternity?
In the aftermath of the Ritual of Night, everything has changed.
The Eight Immortals have catastrophically failed to stop Kihrin's enemies, who are moving forward with their plans to free Vol Karoth, the King of Demons. Kihrin has his own ideas about how to fight back, but even if he's willing to sacrifice everything for victory, the cost may prove too high for his allies.
Now they face a choice: can they save the world while saving Kihrin, too? Or will they be forced to watch as he becomes the very evil they have all sworn to destroy.
