Honor of the Clan by John Ringo & Julie Cochrane (Aldenata/Posleen series)

Lieutenant General Michael O’Neil is called back to Earth to fight the Bane Sindhe underground. He has no idea his presumed dead father Papa O’Neil and daughter Cally are leaders of it.

When the Darhel hire assassins to kill the relatives of the underground, they strike back hard. When they also start killing off the Indowy leadership, the galactic flee to what they think is the safe haven. They flee to Earth where their humans can defend them.

There are many sides to this book. A lot more are explained about how the galactic society work. At least we learn a bit about how the races in it percive how it work. We also start to see forces behind the scenes.

I am looking forward to the next book Eye of the Storm.
