The Silver Skull. Rove City, #10

It's been one year since Amarok offered Maybelle a job aboard his vessel, and she hasn't heard from him since. Anger, concern, and irritation towards him have plagued her, but now all she feels is worried-and bored. Her father has been on the straight and narrow, has a new job, and is taking care of Maybelle's sisters competently. And Maybelle feels adrift and unsure of what her future holds.  In one last effort to reach out to Amarok, Maybelle agrees to a strange task: collect a mysterious item hidden in a bot sent to the mechanic's shop where she works, and deliver it to the resistance.
Maybelle has heard of the resistance, and after some initial hesitation, she decides it's worth the risk, especially if it leads her to finding out what happened to Amarok.  But one task for the resistance leads to another, and Maybelle finds herself dragged into a web and of intrigue and danger far more complex than she ever could have imagined.  This is the tenth book in the Rove City series, and the second installment of Maybelle's story.
