Consider two books : "The Old Man and The Sea" and "Kon Tiki".
Now please give a name to this group of books, highlighting what they have in common and which is as specific as possible compared to other books.
For example: "sci-fi books with dragons" (which is obviously not the case here, just an example of format to follow) Provide two versions of response separated with exactly 6 asterisk symbols: ******.
