Prinz Eugen, a Fleet from Another Dimension, and a Maid Corps

P.S. The original main plot of this book went off the rails, but I love Prinz Eugen too much to drop it, so I'm starting the book over.

Rebooted version: A modern-day office worker thinks she's encountered a portal to another world. Instead of being sent to a land of swords and magic, she's rescued by her future self.

Her future self has already become the ship Prinz Eugen, and turns her into Prinz Eugen as well.

Day One

Prinz Eugen: The greater the power, the greater the responsibility. I have to save the world.

Day Two

Prinz Eugen: Maybe saving the world isn't worth the trouble.

Day Two

Prinz Eugen: Reality is a garbage game. I'll build a paradise of my own.
