A really interesting magic world, with a great cast of characters. Nicholas was annoying at first (spoilt rich kid), but he grows on you. I loved Joanna and Esther. And all of the MCs lives were a bit of a raw deal, which was thankfully all resolved happily by the end. 

Also, this should be tagged by storygraph as an LGBT+ book, as Esther is bisexual and in a relationship with a woman.
