⭐⭐⭐⭐⭐

This book was such a fun book to dive into. It is beautifully illustrated with drawings that look like they were hand drawn. It is laid out exactly like a travel journal. With entries dated and handwritten. Pages with smudges, and even extras taped to the pages. All that, plus a very interesting and informative narrative of an anonymous explorer's journey into the rainforests searching for an unknown river that they discovered on a geographical society map. I can see this being a real hit with school-age kids.
