Every student at Valdris Academy knows the rules: when Princess Seraphine calls your name at the Blood Servant Selection, you kneel. You didn't kneel. The fountain in the center courtyard stopped gurgling. A hundred students stopped breathing. And Seraphine - silver-haired, impossibly still - turned those pale eyes on you like you'd just done something that had never been done before. Because you had. She can read every soul in this academy through their blood-scent: their wants, their fears, the little hungers they hide. But you give her nothing. No scent. No signal. No fear. Now the whole school is watching to see what the princess does with the one person she cannot read.
