Skypunk Princess by David Colello

Sometimes it takes a Princess with a plasma sword to pick up the pieces of a failed world. In the aftermath of climate disaster and the fall of human civilization, a brave few have formed new societies in harmony with nature. Now the AI cities are moving to eradicate these rebels.

Eliana Skybound is an elite Sky Ranger, who charges into a swarm of drones with no fear. Her nanofabric wingsuit makes her a powerful force, but even she has her weaknesses.

Leva Kailani is a Mermaid princess who has yet to fully choose her biohacked form, which makes her a fierce crystalline scaled distraction of the best kind.

After tragedy strikes, their love has a chance to remake the course of history, but only if they have the strength to endure.
