Reasons for not liking this one ..
.
Too slow with too much detailing ..which definitely spoils the purpose in a thriller..
.
I never felt that it's a thriller. Just coping with their own lies and being scared but nothing scary happend..
.
Ofcourse predictable. 
Like each and every twist was predictable (if you call them twist)
.
Also nothing new in plot .
This story of liars is around for really long ..
It's like she dived into some old plot ..
.
The protagonist was wary of everything. always thinking of what will go wrong. She was nothing like that carefree lair they said they were when they were young ..
.
Also the title and the suspense are forced to compliment each other ..
.
And many more 
I don't want to think that I wasted my time in reading 450 pages to find mistakes
So I am stopping.
.
Yeah give this to someone who reads thrillers very rarely. Only they can love it ..
