Iron Sunrise

Bestselling author Charles Stross’ novels have garnered numerous awards and nominations, including several Hugo, Nebula, and Locus Award selections. In Iron Sunrise, a godlike future-being known as the Eschaton has enabled humans to achieve interstellar colonization and near speed-of-light travel.
Just before planet Moscow is vaporized by an unnatural star explosion, its ruling body launches a misguided counterattack against the innocent neighboring system of New Dresden. The strike can’t be recalled without a code known only by a handful of government officials—and they’re being assassinated one by one.
Now it falls to U.N. operative Rachel Mansour to protect the final codeholder and find out who’s behind this galactic set up. But her best hope lies with Wednesday Shadowmist, a teenage girl who doesn’t even know she holds the answers.
“Compelling space opera and cutting-edge tech with a tasty dash of satire … Stross skillfully balances suspense and humor throughout … Offering readers a fascinating future that seems more than possible.”—Publishers Weekly, starred review
