"For as long as Gemma can remember it's been her and Mum against the world. They're as close as can be, but deep down she longs to get to know the rest of her family - Gran and Mum's brother Joe - the family Mum turned her back on around the time Gemma was born. With the summer holidays approaching, Mum is invited on an adults-only holiday. Gemma spots a chance to uncover the story behind the family rift and convinces Mum to let her stay with Joe. He's the perfect uncle - fun, friendly and generous, and even signs her up for tennis camp. But Gemma can't shake the feeling that he and Gran are keeping secrets. As the truth emerges, can Gemma find a way to bring her family back together?"-- Provided by publisher.
