I think I enjoyed the first one better. (It's been so long that I can't remember exactly what it was about.) And I doubt there are actually any teachers like Mr. Terupt—humans just can't be that intuitive and self-sacrificing. It's really nice to read about one, though, and to have something to aspire for.
Since there are seven POVs and the story spans a year of events, it's extremely fast-paced. Like telling someone the story of your life but only hitting the really important parts. I didn't mind it so much, but I did feel like it hindered my ability to get invested. No sooner had one subplot started than it was resolved.
All in all, though, really good and engaging read. I'll definitely read the others when I can get ahold of them.
