Star Raider: The Complete Serial

Cassandra Marx is a thief, and a good one. This time she got greedy, though. She swiped a priceless artifact from Carmody, the most powerful man on Hesperus. He's been beating his daughter, Lark, so Cassie took the kid too.

Now Carmody is tearing the galaxy apart hunting Cassie down. The artifact isn't just a priceless relic of a lost civilization. It's the key to a galaxy-wide conspiracy. Cassie needs to figure out the significance of the ancient egg, but with bounty hunters and mercenaries hounding her from one end of the galaxy to the other, she and Lark have another puzzle to solve -- how to stay alive.
