Lost Souls and a Demoness

After thousands of people suddenly vanish from Earth, former gymnast Jade Callian finds herself thrust into an endless dungeon filled with magic, monsters, and far too few instructions. When Jade receives a mortal wound soon after her arrival in this new world, she is forced to pick a new race that has the power to save her. There's just one problem: Her only choice is to turn into a succubus.

The clock is ticking for Earth, and in more ways than one. Dangerous monsters are pouring out of the Labyrinth, dimensional events scour resources from the land, and beneath it all, demonic plots begin to bear fruit. Facing all this as a succubus wasn’t Jade’s first choice, it didn’t even make the list, but that ship has sailed. If she wants to save the world, she’ll have to leverage every advantage: Shape changing, seductive charm, and all the bonuses that come from wearing embarrassingly revealing armor.
