Cursed with the sight and torn between forbidden loves, she will make the ultimate sacrifice. Arden Archer is cursed: she can see the Unseelie fae. It's a gift that sends the women of her family to an early grave. The only way to break the curse is to offer herself up as the Tithe. Every seven years, the faerie regents pit cursed humans against one another, offering salvation to both parties. This year, Arden is one of those human competitors—a Heartless—and with the help of Unseelie Mavek Midnight, she intends to win. That is, until Eskel arrives, unearthing secrets and planting doubt. Can Mavek be trusted? Is there more to the Tithe than what Mavek had told her? Torn between the Unseelie regent she's loved and a human boy with a dark past, Arden must discover the truth before All Saints' Eve, or risk losing her soul to a beautiful monster.
