Thank you Netgalley and Delacorte Press for the ARC in exchange for an honest review!

“Gaslit” by Megan Davidhizar is a psychological thriller that punches with emotional weight, slow-burning suspense, and a vulnerable but determined heroine you can’t help but root for. It opens with heartbreak and ends in bittersweet clarity, unraveling themes of trauma, mental health, grief, and the terrifying uncertainty of not knowing whether the danger is real or all in your head.

When a babysitting job turns deadly, 17-year-old Ella finds herself at the epicenter of a tragedy: a gas leak claims the life of her aunt and leaves her two cousins unconscious. Ella is forced to make a devastating choice—who she can save—and she’s left grappling with not just the loss, but the guilt. Already reeling from a recent brain tumor diagnosis, Ella's world grows even more fragile as her physical symptoms worsen and her grip on reality begins to waver.

What makes “Gaslit” particularly compelling is Ella’s singular voice. Despite her tragic circumstances, she’s full of optimism, fierce determination, and an appreciation for life sharpened by her own mortality. But her strength also isolates her; she insists on solving the mystery surrounding the gas leak alone, even as her health declines and the possibility of hallucinations clouds her judgment. Can she trust what she sees? Can she even trust herself?

The plot is layered with tension and empathy. Suspicions immediately swirl around Ella’s aunt’s boyfriend, and though some twists (especially one involving Ella herself) may be predictable for seasoned thriller readers, the emotional stakes are what drive the story forward. This isn't a thriller that relies solely on shocking reveals, but rather on deep character work and emotional resonance.

Megan Davidhizar masterfully balances psychological suspense with poignant introspection. Ella’s slow unraveling, both physically and mentally, is heart-wrenching to witness. The book occasionally dips into preachy territory, particularly as Ella reflects on life lessons learned through suffering, but these moments may resonate strongly with younger YA readers. The inclusion of an Educator’s Guide shows that the book is especially well-suited for classroom discussions on topics like mental health, grief, and ethical decision-making.

The romance subplot may divide some readers; while I did appreciate the lightness it brings, I also found it distracting given Ella’s dire circumstances. That said, the love interest adds an element of warmth and connection that offsets the darker aspects of the plot.

The climax is raw and emotional, revealing painful truths that feel both inevitable and gut-wrenching. By the end, Ella learns she doesn't have to carry everything on her own, and the arc of her cousin Chris—whose own actions come under scrutiny—adds another layer of tragedy and complexity. The ending is bittersweet but satisfying, offering closure without undermining the heavy emotional journey.

Overall, “Gaslit” is a heartfelt and suspenseful YA thriller that blends a gripping mystery with a tender coming-of-age story. With its emotional depth, well-drawn characters, and themes of resilience, it’s a strong pick for both teens and educators. Perfect for those who like their thrillers with a pulse and a heart.
