It's not exactly a read with pure characters, but more so how a group of flawed characters brings together in. While you may dislike them at first, it explains everything and their motives.
Theres a lot of things I dislike however, is that there seems to be no redemption arc, but that just might be the realistic aspect of the characters. However, it seems to be that all the characters just have a simple motive or an easy tragedy story. It's not a story to really be dwelled into, but just a quick 3-4 hour read that makes you think a bit.. irritated? Not because of the character's, but just because.. It just drags it on for so long.
