Stars uncharted - S. K. Dunstall

Captain Roystan is a cargo runner who has stumbled across the find of a lifetime: a disabled exploration ship and its valuable contents. His engineer, Josune Arriola, said her last assignment was in uncharted rim. But she is decked out in high-level bioware that belies her backstory. A body-modification artist, Nika Rik has run afoul of clients. She has to flee off-world, and is dragging along a rookie modder, who seems too experienced in weapons and war. Together this mismatched crew will end up on one ship, hurtling through the lawless reaches of deep space in search of unimaginable riches.
