Lily is a nerdy trans woman working a dead-end job in tech support. She gets hit by a truck on her way back from work and awakens in a cave, dressed in fantasy cleric garb with a massive hammer at her side. It turns out she was summoned to assemble a party of champions and get them strong enough to defeat the Prince of Shadows. There are some odd details to this Chosen One situation though: being reincarnated gave Lily a vagina, and the way she strengths her divine powers is by having sex.
...anyway, read this if you like the idea of a genre-aware trans girl making snarky comments and getting railed by fantasy heroes.
