My favorite part about this book is that the wolves are not tame or pets, and rust clearly stated. Wolves are wild animals through and through. I love the respect that this book created for nature in general!
I'd also be interested in more of the history that surrounds this book. Russia has a long history that I don't know a lot about and the book isn't really cemented in the history, it's just vaguely 19th-20th century.
