Phoebe lived the everyday life of a normal 14-year-old girl, just trying to survive eighth grade. But when her friend Amanda suddenly started acting different, it's obvious to Phoebe that the problem was bullying. However, the problem seemed to fade away for Amanda as soon as her new boyfriend entered her life. Phoebe thought that maybe Amanda learned that what the bullies said didn't matter, and moved on.
But on a Monday that finally seemed like a good day among bad, Amanda suddenly loses half her hope--but Phoebe's life is oddly the one effected. The next day, her life starts falling apart, piece by piece, until there is seemingly nothing left.
Confused, lost, hurt, and hopeless, Phoebe meets up with a few other peers who are trapped in the same situation. Together, they slowly realize that their entire life was a lie, and learn that they are not even the species of human they thought they were.
Allegra, known to everyone as Alli, is almost 16 years old and feels different. While her classmates spend their summer holidays on exciting trips, Alli and her single mother are stuck with the routine of their small train station kiosk. She is far from popular at school, and at home, silence often fills the air. But recently, Alli has noticed something changing within her. Her senses are becoming sharper, her instincts more intense, and she feels that something deep inside her is awakening-something she can't explain.
What might seem like ordinary puberty turns out to be much more. Alli begins to perceive the world around her differently, as if she doesn't quite belong. Her mother watches these changes with concern but remains silent, keeping Alli at a distance.
One day, when Alli makes a strange discovery in the old garden shed behind their house, questions start to arise: Who is she really? And why does she sometimes feel like a stranger in her own skin?
Alli has no idea that she is at the start of a journey that will forever change her understanding of herself and the world. A secret her mother has been hiding for years is about to be revealed-a secret meant to protect her from a threat far beyond anything Alli could ever have imagined.
