Rimrider by L. A. Kelley

Orphan, pirate, spy.

Before his murder, Jane Benedict’s father orders her to memorize a mysterious code. Now, she and her brother, Will, are wards of United Earth Corporation. To evade the company’s deadly clutches, Jane leads Will on a desperate escape across the galaxy aboard the Freetrader smuggler ship, Solar Vortex. She discovers her father’s code identifies a secret cargo shipment, and the trail leads to the planet Rimrock and the infamous prison complex of Golgotha. Undercover as a spy, Jane stumbles into a conspiracy that can spell doom for the entire Freetrader cause and the extinction of an alien race.

Piracy, intrigue, romance, and a daring rebellion from Earth wait on the planet Rimrock. Will Jane Benedict answer the call to adventure and find new purpose on the galactic rim or will death for high treason be her fate?
