Lust Hex by Rachel Higginson (epub) Blood Spell Book 1
Fallon Hart is a vampire princess stuck at a boarding school she hates, with peers she hates, with a witchy bully who she especially hates.
Evren Emerson is a total villain. Cruel, hot, and constantly in her business. When a spell goes awry and rebounds onto the two of them, they’re suddenly entangled in a game of lust that neither knows how to win.
Now they must figure out how to break the spell without ending the world. All while Fallon resists the forbidden temptation to bite Trinity Prep’s golden boy.
