Hellburner by C.J. Cherryh
A twisting labyrinth of politics and deception with the new weapons system, Hellburner, at the center of it all. In this story, we have the whole gang from Heavy Time reunited as they rally behind Dekker to pilot the new Hellburner spaceship. What they crew doesn't know is there is lots of behind the scenes jostling for power and money by the UDC, the Fleet, Earth Company (EC) and others. At times I felt like I was just on the edge of not knowing what's going on, but it was a tense, and gripping novel all the way through. In comparison to Heavy Time, there is more non-stop action and intrigue in Hellburner, but I really enjoyed the mundane details of asteroid mining, their time off on R2, and how the ASTEX (the company) works. These two books truly do work together.
In the novel, there is some chatter about the enemy, Cyteen, and their robot warriors. I shall have to keep reading more Cherryh novels to become more immersed in this world. I haven't been this hooked on a series since The Culture series by Iain M. Banks.
