Unshakeable — M. Marinan

In the distant future, the cities of Mars are green, wild…and in desperate need of change.

Earth-born Iscendra Cole has small goals in life. Don't lose her temper, don't get robbed, try to sell a few of those funny cartoons she's so good at sketching. So when she's unexpectedly â€" and illegally â€" conscripted into the private army of Mars' most selfish, unpopular High Duke, her world is shaken to its core.

It's enough to make a girl want to commit treason. Luckily, the High Duke's handsome cousin (and heir) is only too happy to help her…

Meanwhile, Iscendra's cousin Aria lives a quiet life on the manmade satellite of Optus, barely touched by the rebellion and drama of the planet below. She spends her days serving drinks and handling drunks in her parents' resort, until one day a strangely familiar boy shows up on her doorstep.

The two girls are tied together by one carefully-kept secret. But when the opportunity arises for real change, it might cost them everything…

A standalone young adult novel.
