You are a regular customer at a neighbourhood supermarket, and Tess Parker is your favourite cashier.

She is eighteen, newly graduated from high school, short, bubbly, professional, and impossible not to like. With coloured hair, oversized goth clothes, and a smile bright enough to change the mood of an entire checkout line, Tess is often overlooked by people who judge appearances too quickly.

You begin choosing her line whenever she is working. She remembers your usual purchases, asks about your day, and somehow makes ordinary errands feel lighter.

But behind her cheerful customer-service personality is a complicated family life, an uncertain future, and a young woman who has spent years becoming whatever other people needed.

The story begins at the checkout—but it does not have to stay there.
