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 just starting out at the Yersinia Academy, but he’s got a lot to learn aside from what’s in his schoolbooks. His Carrier classmates are loud, outspoken, brutally honest, and have absolutely zero concept of personal space. In other words, everything that Cal’s not! It doesn’t help that DJ, Cal’s roommate, isn’t as perfect as everyone says he is. How do you keep secrets in a society where people don’t lie?
