Magic is in Delilah Bea's blood. Her absentee father is the world's most famous cursebreaker, while all the women in her family are fated to never find true love. So when Delilah sets out to complete her magical Calling and gain her full powers as a witch, she has the perfect task in mind--breaking the Bea family curse.

But Delilah's Calling is hijacked by Kieran Pelumbra, the spoiled son of the most powerful family in the country, and breaking his curse suddenly becomes her official assignment. Every generation, a pair of Pelumbra twins is doomed, with one twin draining the other of their life and magic. Kieran grows weaker while his sister, Briar, becomes...something monstrous.

As Delilah and the twins set out on their quest, they quickly realize that breaking the Pelumbra curse isn't going to be simple. For one thing, the rest of the Pelumbra family doesn't actually want their curse broken--and they've sent hunters after the trio to ensure they fail. For another, something about Briar gets under Delilah's skin, distracting her and making her want to kiss the perpetually grumpy look off her face. But with time running out for the twins and Delilah's own true love curse getting in the way, they may not stand a chance of finding their happily ever after.
