From the author of the USA Today bestselling Priest and New Camelot series comes the third in a high-heat, gothic, dark academia fairy tale full of lantern-lit rituals, foggy moors, and obsessions that last for a lifetime. Rebecca and Delphine's story comes to a head as Thornchapel unravels alongside everyone inside it.

The genius and the sunshine girl. As children, we fought bitterly and often, bickering every chance we got.

But then we grew up. Then we came back.

Delphine Dansey carries her heart on the outside of her body; she’s looking for love and chasing dreams. She’s spoiled and selfish, the kind of beautiful that’s made for money and fame. But somehow she’s ended up in my keeping: a pretty submissive I can’t seem to resist, a lover who obsesses and tempts me.

I thought I’d locked my heart away a long time ago, along with all my other weaknesses. But some doors won't stay closed, no matter how hard I fight to keep them shut. She unravels me, just like our friends are unraveling, just like Thornchapel itself is unraveling.
