The Rules of Survival

This book was very different from the books I usually read. It's about Matthew, Callie and Emma and their struggles with their psychotic mother, Nikki.
This book is sort of like a journal as well, and it's written like a letter. (The way it's written is like an eyewitness account. You see the story through Matthew's eyes, and he's writing it for Emma since she was a baby when these events happened.)
It goes through Everything from start to finish, from the meeting with Murdoch to Nikki coming home from her jail sentence.
Overall, I have not read a book of this...kind.
