I guessed the twist almost immediately which kind of took the intrigue out of this novel. There's big swathes of the book where nothing really happens so it could have been a third shorter than it was. I also didn't like any of the characters but that's not a deal breaker for me if they're well written but they're a little cartoonish in this. The duality of the twins nature was particularly polarised and I understand why but it just felt clumsy. The male character, the main one, was just a twat and I didn't care at all what happened to him at any stage. The twins parents were also completely one dimensional and odd.

The writing isn't terrible in terms of the plot and it did keep me reading so it was engaging to a point. At the end though I was mainly reading to see if I was right rather than because I cared. It was a bit meh.
