I rarely give bad reviews to book series, sometimes it is not my style or interest but this series was my groove, I loved the concept of the books, the first three books made sense and had a strong plot and compelling characters, book 4&5 had growing characters but then the world got away from the author and he lost plot-line, the characters became childish and short-sited. There were double and triple crosses for no great reason except to wrap up the book. It had a strong concept, good start to the series but fell apart, it ended horrifically and made me feel that I had just wasted 70+ hours listening to the story, it had a “lost” ending. I was enjoying it then crashed and burned beyond saving.
