So I finished reading Before I Go To Sleep.
It was ok, a good idea, but it was a bit predictable tbh... I saw the big plot twist coming all the way throughout the book really, so when it came there wasn't really any big revelation, and the very end of the book wasn't very satisfying either. But a decent story, a bit basic, but something different nevertheless.
I'm currently reading The Night Circus.
Utterly fantastic!!
