Alright so this is a really fun light fantasy that pulls a lot of really commonly used and enjoyable tropes like the unknown chosen one with immense power, school for the magic and naturally a Victorian-ish setting and time.

So I read this via audiobook and I have to absolutely recommend this format. The narrators are fantastic and the comedic lines are delivered perfectly!

I am always a sucker for a girl finding the Draco of the school and then deciding to hang with her Ron and Hermione instead and then they stand together to defeat a great evil (Charmed anyone?). Sarah develops quite a bit over the story and I'm very curious to see what she'll do with her powers in the rest of the series but also how she'll help other changelings as well as how her friends will help her (and vice versa).
