First Alliance, Joro: T ik War, Book 1

The Sandradene is the first starship from Earth to go beyond the bounds of the solar system to track a radio signal from 1977 to the Sirius star system, 8.6 light-years away. It isn't about the journey, but what they will find at the other end. Liara and Dominic Marshall are back with Christine Gamble and the ship's crew. It was meant to be a science mission. But it turns into conflict at first contact. The Sandradene and her crew were not expecting war, but now they must face it or they will perish.
