I'm an adult who reads a lot of YA and middle-grade fiction. While well done, The Green Glass Sea (Green Glass #1) by Ellen Klages seemed to me to be likely to appeal more to adults than to tweens and teens. Part of the charm of the book was having famous people, like Enrico Fermi, just showing up as dinner companions and other incidental scenes. But if you don't know who they are, then some of the interest is gone.
Dewey is a great gal, a nicely done budding young female engineer and tinkerer at a time that many fewer women were entering science. On the one hand The Green Glass Sea had me weeping at the moment of tragedy near the end and staying up to finish, and simultaneously wondering if the sob story background added or detracted to the story.
