The "Adventure" series is a collection of children's adventure novels by Canadian-born American author Willard Price. The fourteen-book series chronicles the exploits of budding teenage zoologists Hal and Roger Hunt, as they travel around the world capturing exotic and dangerous animals for their father's wildlife collection.

Shortly before his death, in 1983, Price commented that:

My aim in writing the Adventure series for young people was to lead them to read by making reading exciting and full of adventure. At the same time I want to inspire an interest in wild animals and their behaviour. Judging from the letters I have received from boys and girls around the world, I believe I have helped open to them the worlds of books and natural history.

Hal and Roger Hunt

The sons of respected animal collector John Hunt, Hal and Roger have taken a year off school to help capture animals for their father's collection on Long Island, after which the captive specimens are sold to zoos, circuses and nature parks. In Amazon Adventure, the boys' literary debut, Hal is nineteen years old and Roger is thirteen years old.

Hal is the typical hero: tall, handsome, and muscular, possessing an almost limitless knowledge of natural history and a caring and trusting disposition. Roger, on the other hand, is an ardent practical-joker, often mischievous but just as resilient and resourceful as his older brother.


Each novel in the Adventure series is notable for its memorable selection of loathesome villains and enemies. Some of these, through their interactions with Hal and Roger, are led to redeem their past misdeeds, while others simply suffer the consequences of their actions. Throughout the series, only one enemy, the cunning "Reverend" Merlin Kaggs, appears as a villain in more than one Hunt adventure.
