Fuller's Mine - Emulation Trilogy, #2

Surviving the end of the world isn't easy. Retaining your humanity is even harder. A small group led by Tyra Martin survives the asteroid in an underground hideout, waiting for the murderous fight over dwindling food supplies to end. Just as they begin considering a return to a normal life on the surface, a tragic encounter drives them back into hiding. Aboard Newton's Ark, Cyrus Jones discovers that their virtual world may not be the utopia James Newton envisaged.
As he and his brilliant son work tirelessly to find a way to return to the physical world, oppression grows unchecked, tearing his family apart. Hell-bent on re-population, the leaders of what remains of the United States steadily sacrifice basic rights and freedoms, especially for women, to achieve their goal. When these three groups cross paths, Cyrus and his family confront difficult choices about love, revenge, and belonging, and he is forced to decide just how willing he is to wield the almost unlimited power at his disposal in order to protect the people he cares about.
