Thea’s parents decide to host a big family Christmas in a house by the sea… even though they are, in fact, about to split up. Thea herself is newly single - her sister and brother are both settled, with children, homes and a future. But Thea’s boyfriend has ditched her in favour of his pedigree dogs, and Thea can’t decide whether or not she minds. There will be copious food and drink, holly and mistletoe, lots of bracing walks and a wintry barbecue on the beach. If it seems an odd way to celebrate the final break-up of a marriage and the Moving On to new partners, no- one is saying so. But then no-one had anticipated that the new partners might actually turn up to complicate the sleeping arrangements. As Cornwall experiences the biggest snowstorm in living memory, the festive atmosphere comes under some strain. Will Thea manage to find some happiness for herself? Will the mistletoe work its magic on them all?
