Query: Review of Ajax

A true story of how this girl grew up on a station in Australia surrounded by dogs, horses, goannas and other creatures, with a native girl for a playmate and a fear of being sent away to school. Her golden half-dingo dog Ajax is a pup at the start and grows up with a fiercely protective love of his owner. They encounter floods, snakes and other dangers. The other half of the tale is 'Tam the Untamed' about her wild white stallion which became the model for 'Brumby'.
