A Kiss of the Siren's Song

If you've been waiting for a sapphic pirate romantasy that actually commits to the slow burn, this is the one. Elora and Sybine are both hiding who they really are aboard the Vindicta, and watching them circle each other while a revenge plot and a hunt for an ancient weapon spiral out of control is genuinely addictive. The world-building is organic and the fantasy elements - sirens, enchantment, ancient magic - weave in without ever feeling like an info dump. Just be warned: that cliffhanger ending will have you immediately hunting down book two.
