Charlie N. Holmberg's The Paper Magician
This was a pretty cute, though occasionally gory, historical fantasy, centered on a young woman who's just graduated at the top of her class at magic school, and she wants to work with metal (each magician can only work with one man-made material), but is instead assigned to work with PAPER, ugh, so boring. Except of course it's not, and her mentor is a handsome young guy, who unfortunately is being targeted by BAD MAGICIANS so she obviously has to save the day. I obviously was super into her dog, A+ adorable animal writing here. B+ otherwise. All three books in the series are 2 bucks each right now for Kindle.
