Query: Too Ambitious a Story

Too many characters with too much back story and too many enemies and too many scenes where you are left not quite sure what was going on. There was just too much going on all at once and chapter after chapter introducing new back story on another character in yet another country while the main story came to an abrupt halt. There was no opportunity to care about the cast of thousands. I didn't finish the book. About midway through I just didn't care anymore what happened.
