I was halfway through "Command Decision" when I had the stroke and my friend Steve very kindly brought it and the last book to the hospital for me. In this book, Kylara starts building her interplanetary fleet and has a number of small battles while Rafe rescues his parents from his father's assistant and then runs ISC. We get information here and there on Stella and Grace, but not as much as before.
Then on to "Victory Conditions" which gives us more battles, Toby's girlfriend's turns out to be the daughter of a henchman of the bad guy, and the bad guy attacks Nexus, where Rafe is. Ky's fleet flies to fight.
This was really a fabulous series. I highly recommend it!
