Architects of Memory (The Memory War, Bk. 1)

Terminally ill salvage pilot Ash Jackson lost everything in the war with the alien Vai, but she'll be damned if she loses her future. Her plan: to buy, beg, or lie her way out of corporate indenture and find a cure. When her crew salvages a genocidal weapon from a ravaged starship above a dead colony, Ash uncovers a conspiracy of corporate intrigue and betrayal that threatens to turn her into a living weapon.
