Cepheid Variable (The Sector Wars, Book Two) - Nicola Claire - Bog

The crew of the Harpy are back and this time they're armed for a battle.
Half the known systems want to kill them. The other half wants to be them. It's hard trying to save the universe when the universe can't make up its mind.
But when a gap appears in the Belt enticing every known species to peek through to the other side, things go from bad to worse.
And that's not even taking into account the rogue Originator Class vessel out of New Earth.
Secret science stations, nimble gunboats, and a missing High Councillor; you'd think the crew have enough on their hands. But there's more. The hack code that took out Zenthia Actual, the seat of the High Council of Zenith, is homing in on the crew of the Harpy. And it's as if it knows who they are, where they are, and what sort of threat they are to its goals.
Either Kael and his crew keep one step ahead of their enemies. Or they get stomped on. Nothing like running for your life in a universe falling apart.
