Sheila Harrison always looks forward to the descent of the summer visitors onto 'Seafret', her tall brick house right on the front at Blythney, in East Anglia. She loves the way her spare bedrooms are full, from June to September, with successive waves of children - schoolfriends of her own three and the waifs and strays sent by the Country Hosts' Association. But Sheila is not prepared for the upheaval caused by one young girl, Anansi, who arrives from a background that Sheila can only guess at. Urban, streetwise, knowing beyond her years, Anansi refuses to be patronised by Sheila's well-meaning attempts to make her feel at home. She looks at Sheila, her family and friends, with eyes unclouded by familiarity - and drops a bombshell. Even when the dust has settled, summers will never be the same again.
