I think it was a good book. A bit slow paced in the beginning, but I think I like that. I didn't know I liked those types of books until now. Amazing story telling, and definitely keeps you guessing, even at the end.
I like a lot of plot lines in a book and this book has that. To some it may seem boring though, so beware.
Especially when random characters would ask who was watching her children. I thought that was a fascinating thing to put throughout the book and to keep consistent.
I feel like the ending is open ended because, i'm not really sure if you find out who killed her?
