"And what does that say about you and me?" I dared, meeting his eyes.

Amber irises lit up once again and he growled, "You will always be my exception."

Now that her uncle is gone, and with him, the demon Abaddon too, Aster Fairwae, once the lost Seelie princess, has finally reclaimed her title and throne. Except that the demon prince left with a promise to return with backup—and took Raven, the brother of Aster's best friend.

Aster's newly found mate, Nox, Night King of the Unseelie Court, searches for Raven while she tries to get a grip on her own small council and court. They are obstinate at best and only agree to work with her and Nox if he drops the Veil separating their courts. But breaking the barrier between light and dark has consequences; ones that Nox is not willing to risk.

Nox's refusal to drop the Veil causes a rift between him and Aster at a time when they desperately need to stand together. The threat of Abaddon's return looms, and secrets about what Aster and Nox really are begin to surface. Soon, they are both faced with the reality that the curse the demon placed on Nox so long ago may not be over—that it might never be.
