The Last Valkyrie

Val Ky Ree, a synthetic intelligence, comes back online after an emergency shutdown that followed a decisive battle. Thousands of years have slipped past, and the Aesir, the makers who built her, have vanished. She is now the only survivor of her kind. Her new purpose is guarding the few thousand humans still alive against the hostile alien powers known as the Compact, as humankind stands close to vanishing altogether. A human man becomes her partner as she works out what she is meant to become. She takes up the role of the last Valkyrie, a legendary figure entrusted with deciding over life and death. Bound by her Warrior Code, she must rely on that discipline and her new power when an ancient enemy returns, one she has to confront by herself.
