A man Jess had never seen before stood holding the flyscreen door open. 'Do you own an Appaloosa pony?' he asked. 'Yes.' 'It's stuck in the cattle grid down near the old drovers' yards.' Jess's blood ran cold. At the start of the summer holidays, the unthinkable happens when Jess's beloved pony Diamond has a terrible accident. Why won't Shara, Jess's closest friend, tell her what happened down on the river flats that day? Jess suspects the worst, and feels as though she's lost not just one best friend, but two. But new friends and new horses come into Jess's life, along with the chance to compete in the Longwood campdraft. And there's one little filly who needs her help... Can Walkabout heal Jess's broken heart in return?.
