I am not a fan of open ended books. It is okay if it is a series but not finishing things is not really my style. You don't know at the end of the book who is the person behind everything and you don't know who the brain is. The story is nice, and the interaction between the 3 main characters is well done. There really is no character that I just hate having on the page. There are sub--characters and they feel real in their dealings.
