The 99% Solution. The Time Weavers, #1

What if you could see alternate timelines?What if you could pick and choose between them?Lucy Montgomery is the 99% -- buried in student loan debt and pissed off at a rigged system. Francis Gordon Woodley, IV, is the top of the 1% -- heir to a corporate empire that can buy or topple entire nations. Manipulated by anarchists, Lucy sets out to destroy corporate power so that classless democracy can bloom into worldwide utopia.
With his oligarch friends, Francis sets out to destroy government, unleash free-market forces, and spawn worldwide utopia.  With Lucy and Francis on a collision course, the Time Weavers race to save humanity. But every time weave they find leads to a hundred-year dark age, except one. But for that one timeline to emerge into reality, Simon must encourage Lucy, the woman that should have been his daughter, to assassinate his mentor's son, Francis.
Simon Wentworth -- confused physicist who believes he can choose the course of history from the intersections of past and future realities.  Fiona Black -- optimistic proprietor of The Intoxicating Page, a bar-bookstore where literature is matched to cocktails. Vladimir "Volodya" Kazimer -- pessimistic Russian hacker whose software calculates the probabilities for different futures. Winter -- cute little doggy.
Together, they are The Time Weavers.
