You know that feeling when you realize you've been present for your entire life but somehow missed living it?

Marguerite Leclaire is eighty-four when she begins counting backward. Not years. Not months. Sundays. Every Sunday she can remember, documented in notebooks with blue ink that stains her fingers like evidence of time spent accounting instead of living.

What starts as a simple inventory becomes an obsession that consumes her present while she excavates her past. Four thousand, three hundred Sundays stretch behind her—Mass bells and market trips, two husbands buried, a daughter raised in the margins while Marguerite documented everything except what mattered.

But memory is unreliable. The same Sunday appears differently in multiple notebooks. Whole months exist as blank pages. Her hands shake from three months of writing, and still the counting won't stop. Four thousand documented. Maybe two hundred left to live.

Some obsessions destroy you. Others finally teach you how to be present for what remains.
