The Only One Left

The first 2/3 of this book were great. I was fully on board, enjoying the storytelling, and happy that nothing too crazy had happened. Then the last 1/3 happened. That's when it devolved into complete and utter nonsensical, unbelievable madness (red herring, twist, red herring, twist, red herring, twist, ad nauseam) until the end. Like what even was this?? So the 3 stars are for the first 2/3 of the book and the last 1/3 can fuck right off.
