The best aspect was that the characters were fully realized in forever--made you really see them as real people, which I've found few authors can do, despite being great writers.
The one thing I noticed that may be a mistake is when Grace thinks of Shelby as 'the one responsible for Cole's death': I thought it should be 'the one who had three deaths on her hands', as she was the one responsible for Beck and Cole's deaths, as well being the one had who killed Olivia.
All in all, a pretty good read, if with a slow start...I give forever a 4.87, linger 4.15, and shiver 3.
