The answers Captain Jonathan “Coop” Cooper and the crew of the Ivoire seek lie in the Boneyards. But they must wait for Boss and her team to dive it, explore the wrecks, and piece together what happened in that faraway place. Boss loves the challenge. Thousands of ships, centuries of history, all play to her strengths. In her absence, she trusts Coop to defend the Nine Planets Alliance against the Enterran Empire. But an encounter from Coop’s recent past shows up to haunt him, an encounter he never told Boss about, an encounter that could threaten her future, his life, and the fragile peace between the Alliance and the Empire.
