The great sorceress Rose is about to graduate. She's to become the only Oneiromancer of her generation and a remarkable one - and Rose rises well to the occasion: she's formidably powerful and strikingly-beautiful, and has a prince trailing her skirts. But when rumour of oneiromancy gone awry reaches her ear,
Rose discovers a secret that wrecks everything she's worked for. A twin sister, deep within the forest, abandoned and hurt and ready to take everything away from her.

In a faraway cottage dwells a young woman named Thorn. Although she lives a relatively peaceful life, Thorn's never been allowed further out than the fence made of roses, and she hates when Jada locks her inside the root cellar. Thorn longs to see the world and find a prince to fall in love with. When she learns she has a sister who owns not only her face but everything Thorn lacks - prince and all - her dread of fading away transforms into a hunger that demands everything she was denied.

Rose and Thorn's encounter sparks more than rivalry. A bond thicker than any strife, shared solely by sisters, tugs at their hearts. They've been isolated their entire lives - Thorn in her cottage and Rose within the gilded cage of expectations - and shouldn't a sister be someone to rely on?

But Rose and Thorn's separation was not by chance. Their fates have been carefully planned at the behest of political scheming, and the outcome is clear: only one sister can reap all the glory and claim the prince's hand, condemning the other to a life of perpetual non-existence.
