Book excerpt: On a night of wild storms, two troubled figures escape from captivity. One is a 15-year-old boy, Samuel Miles, a.k.a. ‘Smiler’, wrongly convicted of theft and sent to a young offenders institution. The other is a cheetah, Yarra, a restless resident of Longleat Wildlife Park. Both are in danger from the outside world – and each other – but somehow their lives become inextricably bound up as they fight for survival on the edge of Salisbury Plain. A fast-moving and compassionate adventure story, The Runaways is the first book in Victor Canning's classic children's trilogy.
