Blood Sugar: An Unsettling but Gripping Character Study

Author Sascha Rothchild makes her fiction debut with Blood Sugar, an unsettling thriller that won’t be for everyone. However, it’s likely to hook those looking for a departure from the typical approach to the genre, which so often pits an innocent protagonist against a killer.
Instead, Blood Sugar is told from the perspective of a murderer. And its devastating opening will serve as a litmus test for many, determining whether they put the book down or read all the way through. The novel kicks off with a bold choice and continues to unravel in surprising ways. And its premise is its strongest quality, with everything falling into place behind it.
Rothchild’s story finds 30-year-old Ruby Simon accused of murdering her husband. Although he died of Type 1 diabetes, the police have reason to believe she was responsible. At the request of her mother-in-law, they begin digging into Ruby’s past. What they uncover paints an incriminating picture.
The irony of the situation is that Ruby has killed people—three, to be exact. Her husband isn’t among them, but her presence during the other deaths casts suspicion on her. Thus begins an investigation that takes readers through the entirety of her life. And the author’s depiction of the main character is nuanced and balanced enough to leave readers feeling more than a little unnerved.
What’s so unsettling about Blood Sugar is that it simultaneously paints Ruby as a cold and calculating monster, but also as a human being. So often thrillers whittle the killer’s personality down to their worst or most evil tendencies, but this story proves that even seemingly kind, well-intended people are capable of the unthinkable.
In a sense, Rothchild flips many of the stereotypical serial killer qualities on their head. Ruby doesn’t harm innocent animals; she cares for them. She doesn’t target people for no reason; in her mind, her victims “deserve” it. And Ruby maintains a “helping” profession and meaningful relationships, her public-facing persona far from what you’d associate with antisocial behavior.
