Runabout

A graveyard of spaceships, abandoned by the mysterious Fleet thousands of years earlier. Boss calls it "the Boneyard." She needs the ships inside to expand her work for Lost Souls Corporation. Yash Zarlengo thinks the Boneyard will help her discover if the Fleet still exists.
Boss and Yash, while exploring the Boneyard, discover a small ship with a powerful and dangerous problem: The ship's active anacapa drive.
To escape the Boneyard, Boss must deal with the drive. Which means she'll have to dive the ship on limited time and under extremely dangerous conditions. And she can't go alone.
A heart-stopping adventure that continues the thrill ride of Kristine Kathryn Rusch's award-winning Diving series.
