Two ex-step-siblings. One beach house. Zero chill.

Archie Forsythe has two weeks left in the South Bay beach house his father gifted him but now wants back as part of a messy divorce. Archie’s plan is simple: stall, stay quiet, and finally launch his surf wear brand without his father’s money or control.

Piper Quinn has nowhere else to go.

With an internship at a high-end fashion label and rent in LA out of reach, she moves into the beach house her mom swears is rightfully hers. There’s just one problem: Archie’s still there—and he’s not leaving.

They haven’t spoken in years. But now, stuck under the same roof, they’re picking up right where they left off…with bickering, boundary-pushing, and a prank war that escalates fast.

She hides his towels, dyes his hair, and slips self-tanner into his face wash. He hides her coffee, hijacks her alarm clock, and swaps her perfume with garlic oil. But somewhere between the sabotage and the stolen glances, the tension starts to shift.

Maybe the only thing worse than sharing a house with your ex-step-sibling… is realizing you don’t want them to leave.

A warm, slow-burn romantic comedy full of beach vibes, sharp banter, and sweet enemies-to-lovers tension. Perfect for fans of Beach Read, The Hating Game, and People We Meet on Vacation.
