This was a very well written, suspenseful and twisty mystery/thriller. It was cleverly plotted so that each new development had me eager to find out what happens next.
Gone Girl starts with Amy disappearing on her fifth wedding anniversary and is told in two alternating story lines, one by Nick, the husband, and one by Amy, both narratives are about 6 years apart in time and collide close to the end.
There were slight inconsistencies with some of the plot twists (yes I Googled it!) and because of this the novel lost some points but overall this is a highly entertaining piece of escapism.
I will definitely be reading Dark Places and Sharp Objects very soon.
