Upgrade

Logan Ramsay works for the Gene Protection Agency, which polices illegal genetic engineering, the practice that devastated the world a generation before. After an accident exposes him to an unfamiliar viral agent, his body and mind start to change. His focus sharpens, his reflexes speed up, and he thinks faster than the people around him.

The cause leads back to his mother, Miriam, a brilliant and controversial geneticist who is presumed dead. She left behind a plan for the future of the human species. His estranged sister, Kara, means to carry that plan out across the whole world.

Logan's abilities keep growing faster than he can control them. He has to decide what he is prepared to do to his family, and to himself, to stop his sister. His wife, Beth, and their daughter, Ava, are caught in a conflict he never chose.

The story is a near-future science fiction thriller. It begins in Denver and moves from small-town Montana to New York City. The pace is fast and propulsive, and the tension is personal as much as global, since the threat comes from inside Logan's own family and his own changing body. It is a standalone, so no earlier reading is needed.
