Nightschool, Vol. 1 — Svetlana Chmakova

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?
