Dan’s little brother narrates the tale of Diesel the ‘wonder dog’ and his relationship with his blind owner. The pair do everything together, crossing the city to allow Dan to play in a band, visiting the park (a delightful illustration shows the pair on a windy day when Diesel ‘watches the world’ and Dan ‘feels the world around him’) and travelling to exciting holiday destinations. Both man and dog are terrified at the prospect of becoming separated (this is depicted by the illustrator as a frightening and bleak world in black and white). One day, their worst fears are realised when Diesel is stolen. Dan is devastated and is trapped at home without his guide dog to assist him. But Diesel the ‘wonder dog’ manages to escape from his captors and make his way home. Reunited with his dog, Dan once again feels like ‘conquering the world’.
