With respect to the previous post, Beryl asked, “What do you mean by a 'lifestyle-oriented book'?”
There could be more than one answer to this. For example, if a fishing vest were designed to carry a book, one book could be on the mechanics of fishing, such as what flies to use and when, while another could be by British Columbia author Roderick Haig-Brown, who wrote meditations on fishing and nature.
A third option could be a book that, on the surface, has nothing to do with fishing but is metaphorically related. Maybe a detective novel, or a book of poems. Or a complete non-sequitir, if that is possible anymore.
