Topside Gn by JN Monk

A wild outer-space fantasy about fixing your mistakes and the friends you meet along the way. When Jo, a headstrong maintenance technician, makes an error that destabilizes her planet's core, she only knows one way to fix things: leaving her underground home for a trip to the planet's dangerous, unruly surface. Soon she's wandering through deserts, riding on the backs of giant beasts, and cutting deals with con artists and bounty hunters. Meanwhile, agents of the core are in hot pursuit. J. N. Monk and Harry Bogosian (co-creators of the web-comic StarHammer) present a wild outer-space fantasy about fixing your mistakes and the friends you meet along the way.
