Though she may be a murderer, Ruby is not a sociopath. She is an animal-loving therapist with a thriving practice. She's felt empathy and sympathy. She's had long-lasting friendships and relationships, and has a husband, Jason, whom she adores. But the homicide detectives at Miami Beach PD are not convinced of her happy marriage. When we meet Ruby, she is in a police interrogation room, being accused of Jason's murder. Which, ironically, is one murder that she did not commit, though a scandal-obsessed public believes differently. As she undergoes questioning, Ruby's mind races back to all the details of her life that led her to this exact moment, and to the three dead bodies in her wake. Because though she may not have killed her husband, Ruby certainly isn't innocent.
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 ... 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 ... The author’s depiction of the main character is nuanced and balanced enough to leave readers feeling more than a little unnerved ... Rothchild flips many of the stereotypical serial killer qualities on their head ... Blood Sugar’s protagonist remains a remorseless killer. But it’s a testament to Rothchild’s writing that she can so frequently get readers to forget this fact ... Getting the audience to relate to and at times root for Ruby turns out to be both the book’s strength and its Achilles heel. As Blood Sugar pushes toward its ending, the novel trips over itself trying to find a satisfying conclusion. One has to wonder if it ties up its loose ends a little too neatly ... While the novel offers plenty to analyze on that front, its ending still leaves something to be desired. Once Ruby’s finished recounting her misdeeds to the audience, the pacing starts to slow. The twists and turns don’t feel nearly as shocking beyond the halfway point. At times, Blood Sugar’s later chapters teeter on the line between a thriller and a contemporary novel ... That shouldn’t deter readers from picking up Rothchild’s debut. There’s plenty to appreciate about this story, including how it upends expectations about what this genre is supposed to be and do. It’s an entertaining tale that grips you in the first half. By the time it slows to catch its breath, the audience will be invested enough that they’ll want to keep reading.
... constantly compels us to reconsider what they thought they already knew ... Rothchild is a screenwriter, so perhaps it’s no surprise that Blood Sugar propels forward at a pace worthy of any bingeworthy television show. Ruby’s morally ambiguous justifications for her own behavior will haunt us well after we’ve eagerly devoured this chilling but propulsive thriller.
... clever and dark ... Rothchild’s unrepentant killer quickly seduces the reader through Ruby’s intelligent reasoning, and, oddly enough, compassion, even when her actions are repellant. Rothchild augments her breezy approach with tinges of dark storytelling. Blood Sugar also is a story about a strong marriage and how grief affects people differently ... Rooting for Ruby is akin to viewers’ feelings toward Walter White in Breaking Bad. No matter what Ruby does, the reader stays on her side ... Strong characters, especially Ruby, complement Blood Sugar, as does Rothchild’s vivid use of the Miami setting.
