Awaken discussion

Hi everyone! I am reading Middle Ground, the sequel to Awaken, but I haven't read Awaken in quite some time. I have forgotten characters, subplots, and I even forgot the ending! Middle Ground makes no sense to me as of now and I don't want to reread Awaken. If anyone could please please please comment and give me a good synopsis of Awaken by Katie Kacvinsky I would be forever grateful!!!!
