The Invisible War: Dark Space, Book 2

Their ship is damaged...

Ethan Ortane has just met his long lost son, Atton, but the circumstances could have been better. After a devastating bio-attack and the ensuing battle, they've fled Dark Space aboard the Defiant to get away from the crime lord, Alec Brondi, who has just stolen the most powerful vessel left in the Imperial Fleet--the Valiant, a five-kilometer-long gladiator-class carrier.

They are low on fuel...

They need reinforcements to face Brondi, but beyond Dark Space the comm relays are all down, meaning that they must cross Sythian Space to contact the rest of the fleet. Making matters worse, they are low on fuel, so they can't jump straight there. They'll have to travel on the space lanes to save fuel, but the lanes are controlled by Sythians now, and they are fraught with entire fleets of cloaked alien ships.

And there is no way out...

With Brondi behind them, they can't go back, and they can't afford to leave the last human sector in the galaxy to the crime lords, so they must cross through enemy territory in the Defiant, a damaged, badly undermanned cruiser with no cloaking device. Making matter worse, trouble is brewing aboard the cruiser, dropping their chances of survival from slim...to none.
