The Goldilocks Genome blends grief, science, and revenge into a fast, unsettling medical thriller. It opens with Wendy Watanabe von Gelden’s suicide from the Golden Gate Bridge, a scene written with heartbreaking clarity as she weighs her odds, studies the geology around her, and quietly accepts her choice. Her death pulls the story into motion, setting up a chain reaction that exposes how a mismatch between her genetics and her prescribed antidepressant, fluoxetine, may have doomed her from the start.

Wendy’s voice is sad, sharp, and painfully rational, and the writing pulls you into her head without melodrama. The small scientific observations she made, even minutes from death, got to me the most because they felt like the last sparks of the person she was. That restraint in the writing made the moment linger long after I turned the page.

Jonas, her husband, is a totally different emotional experience. He’s arrogant, rigid, and weirdly fragile, and watching him spiral after Wendy’s death was both frustrating and compelling. His disbelief feels delusional, and yet very human. When Anne later explains the “Goldilocks effect,” the shock and fury Jonas feels actually rubbed off on me. The data about CYP2D6 variants and how Wendy couldn’t metabolize Prozac correctly made the tragedy feel maddeningly preventable.

The book really hooked me once Jonas shifts from grieving to calculating. His transformation into a methodical avenger is slow enough that I caught myself almost sympathizing before remembering he’s crossing lines he can’t uncross. His “gift” to Wendy’s psychiatrist, a rare 1811 port that becomes his chosen method of revenge, was one of those scenes where I literally whispered “oh no, don’t open that.” It’s twisted, but in the gripping, can’t-look-away way.

What surprised me most is how entertaining the science is. Pharmacogenomics, enzyme polymorphisms, metabolizer types, none of this should feel dramatic, but it does because the book keeps tying the technical details to emotional stakes. By the end, I was thinking less about the murders and more about how often real-world medicine relies on guesswork.

I’d recommend The Goldilocks Genome to readers who enjoy thrillers grounded in real science, fans of Crichton, medical mysteries, or anything that mixes brains with adrenaline. It’s sharp, tense, and surprisingly moving.
