I think that much of what makes Brian Robeson such a compelling figure is the way that his character reflects the life and philosophy of author Gary Paulsen. Brian is an intensely autobiographical creation, and the spirit of personal independence and craving for nothing more than to just be a part of the wilderness—a craving that had its origin in the first book of his adventures, Hatchet—is clearly the heartfelt desire of Gary Paulsen played out on the page, in a situation that he has imagined into being so that he can vicariously live out his own dreams of life in the wild through Brian's unique odyssey.
From what I can tell, Brian's Return is a sequel to the storyline as it runs through The River, rather than through the alternate sequel, Brian's Winter. It's not easy to tell for sure, but references in Brian's Return indicate that Brian had returned once before to the wilderness spot where it had all started with his plane crash, rather than that he had spent the winter out there alone and had learned to survive the experience of the ungodly cold, as was the case in Brian's Winter. Then again, maybe there's a way to reconcile the story so that the reader can choose to go with either sequel as the basis for Brian's Return. Is it possible that the events recorded in Brian's Winter could have actually occurred before those of The River, so that the first sequel could be brought into accord with either original storyline? Readers who have gone through all of the books about Brian will wonder about these things, and there's a lot of information to pay attention to in order to be able to mentally set it all right.
It's just not always easy to readjust to regular life after a shakeup like the one that hit Brian when the small plane he was in crashed and he became stranded on his own in the woods for so many weeks, with nothing to help him survive but a rudimentary hatchet and his own wits. Brian is back home, now, but though he has left the woods behind, the woods haven't returned the favor; he has been changed by the harrowing trials of his ordeal into a different person, and trying to get along in the "real world" as if nothing essential has changed proves to be an impossibility. After crossing a line with a violent act (albeit in self-defense) against a high school peer, Brian goes to see a counselor to help him decide what his next move should be. Caleb, a tall man built like a linebacker but with the thoughtful consideration of a philosopher, coaxes Brian to speak about what it was like living by himself in the wilderness. Having gone blind due to a freak illness several years back, Caleb can imagine the glorious outdoor settings that Brian describes with a rich intensity that eludes most other people, and the incredible tales that Brian tells open a window through which Caleb can once again experience the visual majesty of the world around himself. Caleb soon realizes that there's nothing wrong with Brian; he simply needs the wilderness, and there's nothing that can be done to take that desire out of him now that he's experienced its wonder and lived to want more of it.
With the encouragement and support of Caleb, Brian convinces his mother to let him go back again to the place where he feels he first came to understand his own soul, and live there indefinitely. The trip is not an impromptu one this time around, though, and Brian plans and plots carefully to bring along the exact kinds of equipment that he will need to subsist in the wilderness for a long time. He is going back to where it all started, and of his own volition, but this time Brian will have the tools at his disposal to have a realistic shot at dealing with whatever surprises nature has in store for him.
There is an adjustment period even for an experienced woodsman like Brian, but the real test of his ability to reassimilate to the dangerous outdoors will come when he's faced with a threat so raw and unpredictable that his response could never be tested ahead of time. Only if Brian can face down the greatest terrors of nature will he have proven his ability to become part of that nature and rise above its ever-present perils as a hunter, not becoming one of the unfortunate hunted. Will he be able to make it by himself in a world where eat or be eaten reigns as the supreme law of the land?
I sort of found myself wishing that this book were longer, and covered more of what happened after Brian made his decision to return to the wilderness that had so claimed his heart and soul. Brian's Return is a very short book, and leaves off not far into Brian's latest adventure. The story ends before his time back in the wild really has progressed far at all, and I'm sure that it left readers with a strong desire for a fifth book, a desire that would eventually be satiated with the publication of Brian's Hunt. All in all, I think that Brian's Return is a good wilderness adventure story, with even more to offer from a nonfiction standpoint of describing survival techniques and tips than the previous three Brian Robeson novels, and I believe that anyone who enjoyed those first three will definitely want to read this one.
