Starting over at a new school in a new town is HARD. You have to learn the layout, make friends, avoid making enemies, and do your homework, too. It's hard, but it's even harder when you're going to the Yersinia Medical Academy to be a Plague Doctor, your new roomie's weird, you're now an orphan, homework can involve corpses, you need to solve a mass murder, and you're only here because you're now the Carrier of a plague, like everyone else in Yersinia. How will 15-year-old Callum Martinez cope? And can his new friends help him find who was behind the destruction of his former home?
Cal's starting to settle in to his new life at school when DJ realizes that he's living with a stranger. It seems that for each answer he finds, more questions take their place. Namely, who -is- Callum Martinez, really? And what's an Outsider like him doing at the Yersinia Medical Academy?
