Milo Moody collects lost buttons - each one a story nobody else noticed. When an impossible button starts buzzing in his pocket, Milo does the only sensible thing: he follows it down into an Bellweathers' well, with his fiercely opinionated rescue pigeon, Pippa, tucked against his chest.
Beneath the town lies an ancient machine that's quietly rewriting everyone Milo loves. Mr. Pendleton no longer needs his seventeen clocks. Priya's restless brain goes eerily still. Mrs. Kettleworth stops worrying about her petunias. Nobody notices anything is wrong. They just feel calm. Peaceful. Normal. Milo can see that Bellweather isn't being healed - it's being erased, one worry, one ritual, one wonderfully weird habit at a time.
Now Milo must decide if he will go back down into the dark, past crumbling walkways and a machine that whispers a terrible promise: what if he could have a version of himself without the spiraling thoughts, the obsessive counting, the endless need to rescue forgotten things? What if Bellweather could stay calm, peaceful, and painless forever?
The difficult parts of being yourself are tangled up with the beautiful parts, and people deserve the right to choose - even if that choice means keeping the pain alongside the joy.
