The Woman In The Window by A. J. Finn

I absolutely loved this book, it was so well written, just like an old film noir.
Gripping and claustrophobic at times, you have to feel for agoraphobic Anna, who was a strong and yet pitiful character.
There were so many twists and unexpected turns that I truly didn't know if Anna had gone insane or if she really witnessed what she said she did.
The language was easy to read and the story flowed along at a fast pace, I liked the characters and how the writer portrayed them, especially Anna, who needed to seem weak and yet strong at the same time (and a bit brave/stupid considering all the alcohol she drank with those meds).
I honestly couldn't put this book down and will definitely read more by this author.
