Finished
Invasion! Book 1: First Strike. I'm neither much of a TOS nor Diane Carey fan but I like the novel very much.
I had expected the Furies to be dumb 'demons in space'. Instead, Carey made them likable. In the battles between Feds, Klingons and Furies, there was no black/white, each group carried some sympathy and the almost-peace with the Furies adds a delicious bittersweet note overall.
The next book on schedule is
Invasion! Book 2: The Soldiers of Fear. In addition, I've begun reading
Beowulf and Chaucer's
The Canterbury Tales as part of my university studies.
