The series is about sub-lightspeed travel between solar systems by using naturally occurring wormholes, and all spaceship combat is based around controlling these wormholes and naval-type strafing combat between massive fleets. There's a Klingon-like race of cat people called the Khanate of Orion and lots of orbital bombardments.
