Evasion is the first into a side trilogy set in the Scattered Stars universe but far away from anywhere in the main 6 book series - the ftl "nova" jump drive sets limitations to both space travel and the way humanity expands - essentially there are concentric circles of lesser and lesser tech developments the farther from Earth one is; the main series is about elite nova pilots of Apollo (a system in the next to last truly civilized part of humanity) led by major, latter admiral Kira Demirci whom the home government betrayed, so they had to run to the Outer Rim to avoid assassination; there they tangle with an Asimovian organization The Equilibrium Institute whose theoretical goals are to bring peace and stability to various human clusters, but in reality, they tend to bring chaos and destruction. That is an awesome mil-sf series I reviewed a while ago.
This series follows the only one of the nova pilots who refused to stay and fight with Kira and used his share of the wealth secreted away to buy and arm a freighter, Evasion and headed for the Beyond - that is the area beyond civilization, the wild west of the human galaxy expanding to nobody knows how far and where rules tend to be who has the better guns and the more allies makes them... There are still planets with governments and a semblance of warships, but most things are for sale including law and justice.
With a weird crew - including his on-and-off boyfriend, a former farm boy from a feudal Beyond system who somehow got himself piloting skills in his duke's service and then made a dash for freedom, and a strange doctor of many skills about whom we have hints that they have been running from the Equilibrium Institute, picked up on the way there as his original crew slowly dropped off in the still civilized parts of the galaxy (and now 300 light years away from Apollo and some 200+ from Redward, the Outer Rim system where Kira made her base), Captain Evridiki “EB” Bardacki just wants to keep going, trading for a living and hoping not to have kill again - but the Beyond being what it is, not killing becomes harder and harder to avoid when a crime cartel boss corners EB and offers him a job or else, and truly impossible when Trace, a teen girl stowaway on the run from the same cartel, turns to unwittingly carry deadly secrets in her head... And so it goes with non stop action both in space and on stations and planets, great characters and an excellent finale that promises much for the next two installments.
Excellent and gripping stuff
