How To Market A Book by Joanna Penn

4.0

This book provides a nice and comprehensive overview of how to market a book, with tons of information that's applicable to both self-published and traditionally published authors. Even though the book was published in 2017 (at least, the edition I read was), it's got a lot of relevant information, and not much was out of date (though no mentions of BookTok, obviously!)
Highly recommended!
