Quantum Girls: Book II in the Quantum Girl Trilogy

The second book in the Quantum Girl Trilogy
.
Something had happened to reshape all that was, as both Quantum Girls, mirror images of themselves from parallel dimensions, found themselves trapped in a universe where neither of them had ever gotten a quantum seed, and where alternate versions of them had essentially usurped their lives. How did happened was a mystery that each of them had to solve on their own. Two evil nemeses, one from our time, the other, an artificial life form, the sole survivor of a long-dead universe countless trillions of years in the past. Confronted with the new realities, both quantum girls must now set things right, while battling to save their separate worlds.
