Odd numbers: books I want to read. Mostly literary fiction, with some domestic thrillers, memoirs, and poetry mixed in.
Even numbers: books that don't interest me. I am not saying those are bad books, and if you love them, I am happy for you. I'm just not into certain topics, like religion, fiction about shopping/consumerism, adventure, sports, most types of fantasy (especially zombies and vampires), sci-fi that happens somewhere other than Earth, the love lives of people who are hoping to become royalty, non-fiction about business, and books that grew out of Instagram accounts.
