Allegiant should have been a riveting conclusion to the ongoing trilogy. Instead it was an epic failure. I found both main characters (Tris & Four) to be grossly out of character. Don't even get me started on the END of the book! Plus, it seemed all the bad guys from before that were still alive were the only ones that did end up with a happy ending. Where's the justice in that, for the other characters let alone for the reader?
