I'm about halfway through and am enjoying it quite a bit.
One problem though is how Starfleet is violating the Orion ship. This is soverign territory and by sending people on board to kidnap Reyes and to access the navigation logs they are commiting piracy against Ganz. He was perfectly within his rights to have killed the two security officers IMO. (Can't recall their names at the moment and the book isn't handy.)
If Ganz had commited a crime against the Federation then at least Starfleet would have a reason to board the Omari-Ekron but as it is it looks like Starfleet is the bad guys in this one. Nogura may have been out of the loop the first time but he jumped in with both feet on the second.
