If you go to an online store, and buy four or five books in the genre you're looking for, then that store is bound to suggest books to you in the same genre.

As a random Example, Record of a Spaceborn Few by Becky Chambers, or The Galaxy and the Ground Beneath might be one start of a favourable algorithm of book suggestions. You'd need more than just one author to really get your algorithm going.

Librarians are also usually *great* sources of relevant recommendations. Visit your local library.
