Finding books by Black authors shouldn’t be a challenge. So we built Blackauthored—a space designed to help you discover, track, and obsess over your next read. Because finding one good Black-authored read often leads to needing ten more, Blackauthored helps you: - Filter by genres, tropes, spice level and more to find exactly the kind of mess you’re craving - Track books by Black authors that you want to read, are currently reading, have read, or did not finish. - Explore community-made lists with oddly-specific recommendations that hit the spot - Discover authors’ catalogs in their recommended reading order because accidentally starting with book 4 is stressful enough - Rate your reads with decimal precision because sometimes a book is a 4.5, not a 5 - Stay on top of your reading goals and streaks while pretending you’ve got your TBR under control. - Become mutuals with readers who put you onto hidden gems before the hype catches on.
