It’s near impossible to review this on any level without spoilers. It’s better than most books I award a 3 star rating. I came to the book knowing very little about it - I didn’t even know it was a thriller - only that it had been widely lauded. So the first part which seemed very workaday writing with an obviously unreliable narrator seemed to have big flashing “this is a setup for something” signs. And I guessed what the something was. Which wasn’t a problem other than I was bored to death with the setup. The book improved after the twist and I can see why people really like it but I really don’t want to say any more about that.

A good interesting story which just took too long to find the interesting bit.
