Paulsen followed Hatchet with four additional novels about Brian. In the first, The River, a government agent asks Brian to return to the Canadian wilderness-about 100 miles from his original camp-and show him how he managed to survive. The agent gets struck by lightning and falls into a coma, leaving Brian to construct a raft to transport him to a trading post.
Paulsen revisited Hatchet in Brian's Winter. Paulsen answers (by popular demand, he says) the question of what would have happened if Brian had been forced to spend a winter in the Canadian wilderness. This is an alternate version of the story of Hatchet, in which the survival pack radio didn't work, so he couldn't call for help.
The third additional novel, titled Brian's Return, tells the story of Brian returning to the Canadian wilderness in a canoe, aptly named the Raft, a gift given to him at the end of the book, The River.
In 2003, Paulsen wrote Brian's Hunt, in which Brian finds an injured dog while in his canoe. He thinks that the dog belongs to trappers, so he goes to his Native friends to ask if anyone lost a dog. When he arrives at their house, he finds the mauled bodies of his friends. He finds out a bear killed them and noticed that one of their daughters is missing. He later finds her in a canoe out on the lake and goes to hunt the bear.
