Captain John “Black Jack” Geary races to save a group of Alliance POWs from certain death in this gripping novel in New York Times bestselling author Jack Campbell’s Lost Fleet series.
Alliance prisoners of war are being held at a labor camp in the Heradao star system, which also happens to be the location of the majority of the surviving Syndic warships. Determined not to leave any of his people behind, “Black Jack” Geary orders the fleet to strike hard and fast to rescue the POWs with minimal Alliance losses.

The raid is successful, but victory is short-lived. Geary discovers that the Syndics plan to ambush the fleet with their powerful reserve flotilla in an attempt to annihilate it once and for all—but he doesn’t know where the enemy is located. And as Geary has the fleet jump from one star system to the next, hoping to avoid the inevitable confrontation, saboteurs contribute to the chaos…


“I can understand how you fear failing now, but excess caution carries a great danger in itself. You can’t win unless you try to win, but you can lose by trying not to lose.”


You know..I can’t tell if I genuinely really enjoyed reading Relentless, or if we’re just getting so close to the end that I’m excited again. Relentless doesn’t feel like we’re spinning around in circles anymore. It feels like we’re almost there. We can reach our hand out and touch home. We’re not just doing the bare minimum, we’re not being cautious, we’re basically going all speed ahead to try and get home.

We’re getting closer to Alliance space and Geary is trying to be cautious. He wants to. He is scared. Those few who are closest to him see the signs and verbally slap him out of this. Luckily, this takes no part of the book at all to happen. After this momentary lapse of faith, it is all engines ahead. This lapse of faith also had another side benefit: Geary becomes a better character than he was before.

Resources are still a huge problem. They’re basically out of everything, and they have no way of getting more. It just isn’t possible. They’re going to have to make an end run of things, and hope nothing unexpected comes up. Except they come across another camp of prisoners of war, and are determined to do something about it. It’ll just mean less resources, unfortunately. It has to be done, otherwise they aren’t Alliance.

Relentless is really just a really good setup for the finale of the Lost Fleet. We’re continuing on the same themes we have had so far, but they’re getting more and more endgame.  I have no idea what the next book will have in store for me, but I’m super interested in finding out.
