The Shattering Peace

Synopsis

The truce is over. But has the end begun?

An unmissable return to the critically-acclaimed Old Man’s War series, from Hugo Award-winner and science fiction master John Scalzi.

For ten years a fragile truce has held between the Colonial Union, Earth and the alien Conclave. But the Consu, the most advanced species in the galaxy, are descending into a civil war that threatens to touch every living soul in interstellar space.

Gretchen Trujillo is used to the monotony of work within the Colonial Union’s bureaucracy. But her mundane life ends the moment she’s recruited for a secret mission, where she’s joined by envoys from every powerful faction in space. Gretchen must navigate a web of alien intrigue to uncover a truth that will reshape the destiny of every known species, or erase humans and aliens from the stars forever.

Reviews

John Scalzi writes science fiction that is fun, intelligent and irreverent . . . I haven’t enjoyed science fiction this much in yearsChristopher Paolini, author of Eragon, on the Old Man’s War series
Old Man’s War is classic SF seen from a modern perspective – a fast-paced tour of a daunting, hostile universeRobert Charles Wilson, author of Spin, on Old Man’s War
I enjoyed Old Man’s War immensely. A space war story with fast action, vivid characters, moral complexity and cool speculative physics, set in a future you almost want to live in, and a universe you sincerely hope you don’t live in alreadyKen MacLeod, author of the Lightspeed Trilogy, on Old Man’s War
I can honestly say I can’t think of another book that ever made me laugh this much. EverPatrick Rothfuss, New York Times bestselling author of The Name of the Wind, on Redshirts
