Blood Sugar follows a female serial killer named Ruby. In the first chapter you learn of her first murder and wonder how you could ever find anything good, in Ruby.

This book alternates chapters between the present and past, helping us to understand Ruby and her life. Somewhere along the way, Rothchild shows us a different side of her; someone almost impossible to dislike, and even root for a little bit, as she tries to prove her innocence in the wake of her husbands death.

The first 40% was a quick read, then slowed down until about 70% where the pace picked up and was gripping until the end. I would consider this a very slow burn as far as thrillers go.

I felt the ending wrapped up neatly in a way that didn’t quite sit right with me, but I enjoyed the book nonetheless.

Thank you to Putnam Books and NetGalley for the eARC!
