Scholomance 2: The Last Graduate - Naomi Novik
Tax included.
The dark school of magic has always done its best to devour its students, but now that El has reached her final year -- and somehow won herself a handful of allies along the way -- it's suddenly developed a very particular craving...
...for her.
As the savagery of the school ramps up, El is determined that she will not give in; not to the mals, not to fate, and especially not to the Scholomance.
But as the spectre of graduation looms -- the deadly final ritual that leaves few students alive -- if she and her allies are to make it out, El will need to realise that sometimes winning the game means throwing out all the rules.
