Book excerpt: A Spartan warrior-in-training decides to leave school—and the girl he loves—in this fantasy novella by the New York Times bestselling author. I'm Logan Quinn, the deadliest Spartan warrior at Mythos Academy. At least I was—until the day I almost killed Gwen Frost. Professor Metis and Nickamedes say that I'm fine, that Loki and the Reapers don't have a hold on me anymore, but I can't risk it. I can't risk hurting Gwen again. So I'm leaving Mythos and going somewhere far, far away. I know Gwen wonders what's happening to me, whether I'm safe. I can't tell her, but this is my story.
