4.5 stars towards 5 because it's really good
This book it's like watching a movie, a very good one, with such a great characters, a suspense that will keep you on the edge till the last page and a lot of twists and turns that you'll think you know it all, you got everything sorted out or feels predictable at times, but honestly it's not because the more you read, the suspense gets higher.
I liked the writing, the author has a gift of a great storyteller and the book overall it's very recommendable to any lover of suspense mystery crime and even the TV serials like Numbers because it has a lot of vibe from it and i just loved it.
