I see why this was a polarizing book (even for big fans of Sager) but it was right up my alley. I am NOT a fan of the unreliable narrator trope but it worked so well in this story. It pays homage to the movies without doing so in such a meta, heavy-handed way and it hands out plot twists in true Sager fashion. This book definitely is not for everyone but I really enjoyed it! 

Pros: 
 - character growth 
 - journey of self-forgiveness 
 - fun movie references that work 
 - good psych thrills 

Cons: 
 - drags a bit in the middle (the psych thriller portion goes on for a while) 
 - over explanation of the loose ends which seemed a little unnecessary when you get to the final ending
