Unbeknownst to the galaxy, an ancient race has enslaved an entire world for countless millennia. Now a single thrall has managed to escape and it's up to a teenage girl to help him free his people. But Angela “Gel” Colson only appears to be Human teen. She’s actually a mutant variant from a race of teleporting aliens and she's out to prove herself, but must do so without revealing her powers. Along the way she'll have to acquire a moon, win over a reptilian alien who threatens the future of the enslaved people she's trying to save, criss-cross the galaxy via ancient technology hidden in the soup atmospheres of numerous gas giants, and quite possibly upset the economic stability of a region of space. Ace of Thralls is the third book in the Freelance Courier series of Angela (Gel) Colson, a young entrepreneur with a knack for getting embroiled in galactic-scale issues and far flung adventures.
