What She Doesn't Know.

"Some lines were never meant to be drawn in chalk."

When Rowena Ford agreed to host her younger daughters friends for the summer, she never expected her. Arielle Rayes. sharp-tongued, late-night laughing, dangerously observant. The kind of girl who takes up space without even trying, who makes you feel seen and stripped bare in the same breath.

But Rowena is supposed to know better. Thirty-seven, guarded, freshly stitched together from a heartbreak no one talks about. Arielle is just nineteen, messy in the way only girls with too many secrets and not enough rules can be. And yet, neither of them can seem to stay on their own side of the line.

As days blur into soft mornings and flickering nights, what starts as stolen glances and casual brushes spirals into something far more complicated. With friends in every corner of the house and the shadows of reality looming just beyond the summer haze, Rowena and Arielle find themselves caught in a storm of what they want, what they fear, and everything they're not supposed to feel.
