Some desperate glory - Grand Format

Some Desperate Glory is a thrillingly told space opera about the wreckage of war, the family you find and the path you must forge when every choice is stripped from you. This standalone novel is the highly anticipated debut from Astounding Award and World Fantasy Award-winner Emily Tesh. All her life, Kyr has trained for the day she can avenge the destruction of planet Earth. Raised on Gaea Station alongside the last scraps of humanity, she is one of the best warriors of her generation, the sword of a dead planet.
But when Command assigns her brother to certain death and relegates Kyr to the nursery to bear sons, she knows she must take humanity's revenge into her own hands. Alongside her brother's brilliant but seditious friend, and a lonely, captive alien, Kyr must escape from everything she's ever known. If she succeeds, she will find a universe far more complicated than she was taught and far more wondrous than she could ever have imagined.
