I've worked with the excellent Sexy Little Pages a lot in the past year. Here's a quick sampling of the books they've put out that include my work:
Ticket to Ride
Love of the Game
Silence Is Golden
Goodbye Moderation: Lust
I'm very proud to work with them. Not only are the books gorgeously produced and full of sexy, high-quality writing, they're also committed to an inclusive, body-positive view of sexuality that I really believe in.
So I think they're well worth supporting. Of course, buying books is a great first step. Beyond that, though, you could consider becoming a Patron through Patreon. (May I point out that, not only will this help Sexy Little Pages spread the word about their books to a wider audience, it could also get you free copies of current releases, depending on the level of support you choose to offer).
Patreon is a really cool service that allows creative people a little stability in a time of great uncertainty. Please consider showing Sexy Little Pages some love that way. (You can support them for as little as $1 a month, but if you go up to $5 a month, you get access to free new releases...). If you'd like to check it out, the Patreon page is here.
