fierce, sapphic fantasy about a witch whose mission to assassinate the prince she's betrothed to is compromised by the discovery of a deadly plague - and the beautiful princess intent on stopping it.

After years of bloodshed, Ranka's coven has one last mission for her: travel to the human kingdom, marry the prince, and kill him. Easy enough.

Except the prince is gentle and kind. And it is his sister, Aramis - wickedly smart and infuriatingly beautiful - who seems to be the real threat.

When witches start dying from a mysterious, magical plague, Ranka and Aramis are forced together in a desperate hunt for a cure.

Soon, Ranka will have to choose between the witches who raised her, and the princess she may be falling for . . .
