well, honestly, I liked it. I don't know what is it with Victoria Schwab, but you can feel the bonds, the connections, the feeling between her characters. It always feels real, melts my heart somehow. :))
However, I wasn't her best. I liked it, it was fun, it was fast, it was the best I had among middle-grades, but not perfect. More than 3, maybe closer to 4, but not four.

Four is for perfects.
