I really loved Ruth Ozeki‘s other books, but I couldn't really get into this one. The beginning was nice but the plot kind of stalls for long and it got a bit boring. As a scientist, i didn‘t really love the one sided explanations of GMOs, but whatever. I couldn‘t stand most of the characters, except Cass and I didn‘t feel like Yumi was a good protagonist for this story. I thought sometimes the male characters were written a bit weird.
