Reading the Schooled in Magic series by Christopher Nutall- ten books and I'm loving every single one.

The gist of it-
Modern-day girl of an abusive family gets snatched by interdimensional beings acting on the whims of another universe's powerful being- a Necromancer of the Unnamed Lands. The Necromancer, Shadye, snatched her because he wanted a Child of Destiny, someone who he could use to influence great changes in the world, in his favor (the girl's mother was named Destiny). A powerful, but not by any means equal to Shadye, "Lone Power" magician by the name of Void saves her, and deposits her at the largest magical academy. Ten books of shenanigans begin- but seriously, this is a really in-depth book. It isn't just 'because magic', it's got some real thought-out crap and some real loopy shiz. Interesting characters, amazing writing.
