Really good! I enjoyed Miles and Rhys. They felt like real middle-school kids. I also loved their families, and how it acknowledges the landscape of videogames and middle-school friendships is mch different now. It's hard to compare it to the olden days. 

Now, the story resolutions were half-baked:

All is given rather quickly. There's no real apology, and Miles never explicitly realizes the kids he tryna kiss up to aren't real friends. Real friends don't put you up to bullying, make you feel small for not doing something, or disparage something you enjoy that's not harmful.

There's a second book coming, so hopefully those issues get address there.
