Just my luck

For fifteen years, Lexi and Jake have been playing the same six lottery numbers with their friends, the Pearsons and the Heathcotes. Over dinners, parties, and summer barbecues, they have always discussed the important things and shared a laugh when they won, at most, ten pounds in the lottery. But then, one Saturday night, the unthinkable happens. Their six numbers come up, and everything changes. Lexi and Jake are holding a ticket worth 18 million pounds, and they don't want to share. And their friends are determined to get their share. How far are they willing to go?
