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?

When Alex's sister, Sarah, vanishes and all memory and evidence of her existence is erased, Alex is determined to get to the bottom of her sister's disappearance. What better place to start her investigations than the Nightschool itself? But when she discovers that sneaking into the Nightschool isn't as simple as it might seem, Alex enrolls as a student. But is she prepared for what she might find?

Betrayed by one of their own, the Hunters have become the hunted as their hideaway is invaded by a pack of ravenous werewolves! But it'll take more than a few mongrels to get the better of these kids. Meanwhile, Alex begins advanced training with Mr. Roi. Will he be able to help her find a clue to her sister's disappearance? Or is the home-schooled Alex in way over her head?

The Sohrem is rising, the Hunters are on the move, and Alex is caught in the middle! As forces conspire to draw the young weirn and her allies back to an empty school, the shadow of the enemy who has been pulling all the strings begins to show. But is it the enemy without - or the one inside her - that Alex should fear the most?!
