This is an adventure novel. Some people think it is allegorical, but the author emphasizes that it is not a statement about anything other than a story he made for his children while traveling. He is obviously a well-read person who weaves in great quotes from literature into the beginning of each chapter. Loved that the last one had a Jane Austen quote!
We have a population explosion of rabbits in my neighborhood this spring. They are everywhere in our yard. I will never look at rabbits the same way again!
