Nightspell

Here be ghosts, the maps said, and that was all.

In this haunted kingdom, ghosts linger--not just in the deepest forests or the darkest caverns, but alongside the living, as part of a twisted palace court that revels all night and sleeps through the daylight hours. Darri's sister was trapped here as a child. And now Darri has a chance to save her sister . . . if she agrees to a betrothal with the prince of the dead. But nothing is simple in this eerie kingdom--not her sister, who has changed beyond recognition; not her plan, which will be thrown off track almost at once; and not the undead prince, who seems more alive than anyone else.

Can Darri's warrior heart withstand the most wrenching choice of all?
