The fireflies didn’t just leave Auden Creek. Somebody made them disappear.

When Pip Merritt starts asking why the lights went out of her town, the grown-ups have answers ready: the weather changed, the world got brighter, isn’t it a shame. But Pip has her grandmother’s twenty-three years of firefly counts, a brand-new neighbor with a laboratory in his garage, and a growing stack of evidence that points straight at the old Fenwick mill and at the people who would prefer the whole thing stay quiet.

A big-hearted middle-grade ecological mystery about citizen science, second chances, and the small, stubborn act of refusing to look away.
