This is a fantastic start to the Mythrin series, and I very much enjoyed the read.
The characters in the story are interesting and well developed. I appreciated that they were capable of some level of self reflection and growth, but still also read like the Gr. 8-aged students that they are. There interactions with one another also read as very real.
The setting in a small town in Ontario worked well, especially at the start as Amelia found her new footing after unwillingly being sent there from the large city of Vancouver, BC. As far as I could tell, Dunstone, the town in the story was fictional, but Bow crafted it so well that it almost could have been real (and one or two Ontario towns came to mind as I read the book). Similarly, Bow was deft at creating the entirely fictional world of Mythrin. She included enough details that I felt as if I were in each setting, feeling the cold of the Ontario winter, and warmth of Mythrin along the way.
The plot, too, was well crafted. There was enough action to keep things moving, with enough urgent moments to keep me turing the pages to see what would happen. But, this action was balanced with moments of reflection and discussion that both gave me a rest while also allowing me to get to know the characters better.
Overall, an extremely well-constructed story with very realistic, engaging characters. I am looking forward to reading book #2.
