Three and a half stars, rounded up because I was glad for a change of pace from my usual to jump start the summer.

Things I enjoyed;
Small bits of educational trivia thrown in.
Learning more about Japanese and Korean history, and the racism between the two countries.
The cultural representation of teenage life in another culture.
That it was a pretty quick read (the long dates are because I had other books going at the same time. I read about 60% to the end on the last day.)

Things I didn’t;
At times the characters felt a bit trivial.
Some action felt predictable.
The ending felt a little abrupt... rushed?
The balance in maturity of these high school students felt off. Maybe that was a cross culture thing... but it seemed like at one moment they were way too immature over simple things and the next way too deep and intense and forward thinking.

Overall I’m glad I finished it, wouldn’t recommend someone pay full price for it. Library loan? YES. Kindle for a few bucks? Certainly. Hardcover and keep on your shelf in a long term library? Ehhhh, not my pick. I don’t have plans to reread this one.
