The characters were great as well. Katie was in a completely new country, but she was very headstrong and confident throughout the book. I loved that. The YA world really needs more strong, independent female characters. Katie would not back down or let Tomohiro have the last word. Their witty banter was so amusing to read. Tomo was a very complex character throughout the storyline. He has a lot of depth as well as a mysterious facade. I really wanted to figure him out throughout the book, and I liked what I discovered. His relationship with Katie was pretty good. I understood and felt the attraction and enjoyed seeing how their feeling played out. Even the minor characters like Yuki, Tanaka, and Diane felt realistic.
