A very high 4 star. Probably 4.5

The only reason this is not 5 stars, is because the writing took a while to get used to. I therefore only really started getting into the story around page 150.
But the rest? Was absolutely 5-star material. A few good plot twists and amazing characters. The premise is amazing as well and I am a sucker for school/academy settings.
I can't wait to read book 2.
