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.

Ensnared by deceit and desire. "Falling in love with you could arguably be the worst thing to ever happen to me... And yet," he flung his arms out, "here we are." In the aftermath of the Tithe, Arden faces the consequences of events that both she and Mavek set in motion. Can she prevent the unthinkable? Or is she doomed to a lifetime of grief, pain, and retribution? And what of Eskel and her undeniable feelings for him?

Can Arden, Mavek, and Eskel set their differences aside and work together in order to stop the wicked fae prince out to get them? Arden Archer is an Unseelie. After struggling against the turn for months, Arden has finally accepted what she's become, and what it means for her future, and the future of those she cares about. Even though she's more powerful than a human, she's still no match for Finch, the Unseelie Underground prince out for revenge against her and Mavek for what took place at the Tithe. Finch is willing to do anything to reclaim the throne that was stolen from him that night, even offering a truce if either Arden or Mavek will swear their courts allegiance to him. But Arden knows better. Experience has taught her no good can come from a deal made with the fae, and she's unwilling to risk putting Eskel or her sister in any more danger. With no other choice, she turns to the one person she knows for a fact can help her. It quickly becomes apparent that Finch isn't the only thing she needs to worry about though. There are also lingering feelings that need dealt with. Feelings towards both her boyfriend, and the Midnight King. Mavek Midnight went through a lot in order to keep Arden by his side. Now that it's been done, however, he's realizing keeping ones heart is a lot more complicated than he'd ever imagined. As he struggles to make amends for his mistakes, Mavek is also forced to ask himself how much he's willing to sacrifice in the name of love. Can he accept Eskel Montgomery for the sake of his queen? And, more importantly, can he convince Eskel to accept him?
