The Ursine Agenda - Disunion Series, Book Two

The Ursine were humanity's only allies. Then someone kidnapped their scientists. Now a war fleet is coming - and it's pointed at the wrong enemy. As the Union reels from rebellion and its alien allies prepare for revenge, Commander Matt Ryder goes undercover to find the truth. His search leads him to a criminal empire, a graveyard of stolen warships, and a confrontation with the mentor he can no longer trust. Meanwhile, presidential aide Amanda Chester follows a trail of piracy, illegal research, and political betrayal that leads somewhere far more dangerous than she expected.
