SOLVED Sci fi, female lead security officer on small trader ship, using a small mecha suit [s]

[Mathias Söderberg]

2011-2013 (not sure when i read it but think last 2 years and then it was released recently)

It starts about female who is leaving her mercenary group because they will promote her above captain (above captain don't see action). She wants to be some kind of knight for the emperor and the only way she see that coming is if she accept the job as security officer on a trader with a dangerous reputation.

Her baby is some kinda mecha suit a small but deadly one.
