Mori and River. I loved them together so much. I was SO annoyed with how Mori fought with himself over whether or not he was going to let himself have River, though. I totally understood his reservations, but after the last book with Bailey basically deciding for Harlow that they shouldn't be together, I hated watching it happen again in this book. That said, I loved this book anyway. So many things happened, and it was all so exciting and tragic and delightful and heart wrenching. Everything that happened was something the book needed; pulling in the plot from the previous books, and setting up the next book perfectly. I'm pumped to read the next book!
