Vampire Academy: Shadow Kiss (book 3)

It's springtime at St. Vladimir's Academy and Rose is close to graduation, but since making her first Strigoi kills, things haven't felt quite right. She's having dark thoughts, behaving erratically, and worst of all . . . might be seeing ghosts. Consumed by her forbidden love with her tutor Dimitri and protecting her best friend, the Moroi princess Lissa, Rose is in no state to see the deadly threat that will change her entire world - and make her choose between the two people she loves most.
