Kenna Heron is best known in her village for being a little wild—some say half feral—but she’ll need every ounce of that ferocity to survive captivity in the cruel Fae court. Trapped as a servant in the faeries’ underground kingdom of Mistei, Kenna must help her new mistress undertake six deadly trials, one for each branch of magic: Fire, Earth, Light, Void, Illusion, and Blood. If she succeeds, her mistress will gain immortality and become the heir to Earth House. If she doesn’t, the punishment is death—for both mistress and servant.

And now, well, Sara might still be able to save the world, but in order to do so, she'll have to sacrifice her heart in the process.

My father called them messengers. He once told me they walked among us and that somewhere in this dark and godless city, there shined a faint sliver of hope. I had only to look for the signs. Well, I’ve spent my whole life investigating the inexplicable and all I've found are the unsettling vestiges of iniquity—the evidence of another world shrouded by the obscure. Purgatory to some, where depravity hides in shadows, and girls like me are little more than delicious bites of temptation. Others call it Nightshade.

Jude Maddox knows nothing of love or even light. He knows only his grim duty as the Hand of Death, to lead the Knights of the Eternal Star into a land filled with nightmares and certain demise.
