Nine Billion Ghosts

A woman with no past walks into a Chicago tech firm carrying blueprints that could save the world—fusion power, carbon capture, technologies decades beyond anything known. Reva Temin is hailed as a genius, but Department of Energy official Calvin Draper discovers she has no birth certificate, no history, no DNA matching any population on Earth. What he uncovers is far stranger than espionage: Reva carries the weight of nine billion deaths that haven't happened yet, and powerful forces are already moving to corrupt her gifts.
