In this first story, troublesome twosome Nell and Freddie go on a school trip to a farm, where they pet the animals and learn about how they live, and Freddie smuggles a piglet out in his backpack. He thinks he's saving it from becoming sausages. So Nell keeps it in her bedroom, gives it a bath and gets it involved in bringing a local crime wave to an end (with the help of her hilariously teenaged big brother, Lucas). Then they all go home for tea!From Caryl Hart and Sarah Warburton, the team behind the wildly successful 'The Princess and the...' picture book series, 'The Invincibles' series is perfect for children who are beginning to read alone. Beautifully illustrated in two-colour to make the transition from picture books to chapter books easier and more appealing.Look out for:The Hamster RescueThe Beast of Bramble Woods
