Want other players to keep their hands of your notes? Perhaps it will help if they think the book is just a smutty, nasty little lovestory between a handsome orc and a fair young maiden... Or maybe they'll sneak off with it to read it in their room, I don't know your friends.
For every DnD player and Critical Role lover, I designed a Tusk Love book jacket that fits around an (included) A5 lined notebook.
