This was honestly one of the saddest books I've ever read. I'm not going to spoil too much for you, but essentially it's a reflection of the life of a serial killer on death row told through the perspectives of women he'd interacted with throughout his life. Super sad, super well written, bawled my eyes out multiple times. If you liked the Lovely Bones, you'll like this one too, it has a very similar feel. If you haven't read the Lovely Bones, read that first because it was actually the saddest book I've ever read.
Love crying over books man, it really gets you feeling human โค
