The Regnant War [EPUB ebook] 

The nuclear fallout of the Pernicious Bellum War took humans to the verge of extinction. But what doesn’t kill you makes you stronger, faster, smarter, and so on…or so they say. Add into the mix two-hundred and fifty years, a little genetic manipulation, a few scientific surges forward, and a lot of deception, and the stage is set for the war to end all wars: The Regnant War. Caught in the middle of it all is Alexandria Jaquette, created in a lab and raised to be a weapon. Her ability to see and control gravity waves makes her a desirable asset and both sides want her in their arsenal. The only problem is that she doesn’t want to be a weapon. It’s too bad neither side cares what she wants.
