A book is only the start. What about maps, logbooks, pictures, and everything that doesn't quite fit between the pages? Here is where I've collected extras for the Nautilus Legends. I'll add to it as I go. But be warned... there be spoilers ahead! I'll sort it by book (i.e. if it's under the Free Dive title, you need to have read at least Free Dive to avoid spoilers). Enjoy!
Don't look below if you haven't read Free Dive!
