I looked up the book, it's not that bad. Unless the kid is easily scared, it does seem like a dark humor book for kids. I wouldn't have batted an eye if you gave that to my three year old. She loves those kinds of books.
Eta: The preview I found I could only read up to where she killed the old one during a snow in. If it gets worse after that point then maybe not kid friendly.
