Twenty stories of the best erotic science fiction and fantasy published by Circlet Press, collected together. Funded through a Kickstarter campaign run in 2017-- the year of Circlet's 25th anniversary-- Superlative Speculative Erotica features stories voted on by the Kickstarter and Patreon supporters and reflects many of the genres published by Circlet Press: a little cyberpunk, a little high fantasy, a touch of horror, some superheroes, a bit of space opera, some paranormal... What unites these stories is their quality. The anthology, like the cohort of authors and staff of Circlet Press itself, features characters who identify as lesbian, gay, genderqueer, bisexual, trans, and heterosexual. The erotic activities expressed within the stories cover a similar variety, though it's not an identical match: a gay male author can write a lesbian witch who has sex with a gender-changing demon. What label do you put on that? We call it... superlative speculative erotica.
