Love Potion

A story about a girl who tumbles unwittingly into her favourite book series. Every character is waiting for her: kooky teachers, the chairbound headmaster who speaks through a chattering skull, a bedchamber of rapturous girls, the mysterious Fae, even Killian Viper, every girl's fictional crush, the mean boy whose bed she wakes up in, in her whole new world...
A shame he turns out to be the tightest asshole to live. Many boys are the same. You're obsessed with them for a while, spinning fantasies in your head, and then when it comes to get to know them you discover they aren't the same boy.
Cosmo has a lot to learn in the new and magical school of Greamelts. She scarcely knows she will get through it. Learning magic from scratch and everyone you're meeting being new and never to see home again, all combined with the tortuous tormenting of Killian Viper, is a large army to battle. If she could go back, would she? Is she ready for her own story, that awaits her?
Hearts are indeed a hard riddle to crack.
