Just My Luck by Adele Parks

It’s the stuff dreams are made of – a lottery win so big, it changes everything.

For fifteen years, Lexi and Jake have played the same six numbers with their friends, the Pearsons and the Heathcotes.
Over dinner parties, fish & chip suppers and summer barbecues, they’ve discussed the important stuff – the kids, marriages, jobs and houses – and they’ve laughed off their disappointment when they failed to win anything more than a tenner.
But then, one Saturday night, the unthinkable happens. There’s a rift in the group. Someone doesn’t tell the truth. And soon after, six numbers come up which change everything forever.
Lexi and Jake have a ticket worth £18 million. And their friends are determined to claim a share of it.
