Nightschool: The Weirn Books, Volume 1 (Nightschool: The Weirn Books #1-6)

Schools may lock up for the night, but class is in session for an entirely different set of students. In the Nightschool, vampires, werewolves, and weirns (a particular breed of witches) learn the fundamentals of everything from calculus to spell casting. Alex is a young weirn whose education has always been handled through homeschooling, but circumstances seem to be drawing her closer to the Nightschool. Will Alex manage to weather the dark forces gathering?
