Descent into Hellios: A Colonial Fleet Novel

Rate this book
From beyond her grave, a hero’s final transmission could turn the tide of a galactic war.

Three years after humanity's Final Stand against the Korilian Empire, the Colonial Defense Forces have largely reclaimed the lost colonies. However, as the tide of war shifts against the Colonies again, Admiral Jon McCarthy and Lara Anderson discover a message from a long-dead prescient Nexus Ten amid the ruins of Darian 3. This startling discovery creates the potential to alter the course of the war with the Korilians, tilting the outcome toward humanity’s favor.

Admiral McCarthy and Lara accompany 2nd Fleet and a Marine Expeditionary Force on a mission deep inside Korilian territory. Their target is Hellios, a dark planet hosting a Korilian facility shrouded in mystery. The mission to penetrate and neutralize the complex is perilous, and as a handpicked Marine platoon descends through each level, the stakes escalate. But when they reach a dark chamber in the heart of the enemy stronghold, no one is prepared for what they find.

RICK CAMPBELL, a retired Navy Commander, served on four nuclear-powered submarines, finishing his career with tours in the Pentagon and the Washington Navy Yard. On his last submarine, he was one of the two men whose permission is required to launch the submarine's nuclear-warhead-armed missiles.

Upon retirement from the Navy, Rick was offered a two-book deal by Macmillan / St. Martin's Press for his novel The Trident Deception, which was hailed by Booklist as "The best submarine novel written in the last thirty years, since Tom Clancy's classic - The Hunt for Red October". His first six books were Barnes & Noble Top-10 and Amazon #1 bestsellers, and the 7th and 8th books in the series are scheduled for release in April 2024 and spring 2025.

The 2nd of a 6 book series, I am enjoying his jump into Sci-Fi. I have read his Dad's "Lost Fleet" series, and have read Rick's military (submarine) thrillers. I like that the space battles are a little more practical. No hyper-space, instead it takes time to move from place to place. Weapons and shields must re-charge. Characters are interesting and engaging. I'm looking forward to the next 4 books over the next few months.

Not as good as the first book, but still a fantastic read. This one delves into warring factions in the government and a big secret. That plot twist was a good one - probably a lot of people saw it coming but I sure didn't.

This is the best scifi I've read in awhile. It has its own flavor, more hard scifi/military than I usually read. The strategy of war, ships being sent into battle knowing they'll be lost, it's a very interesting look at the way our military decides what to do in a war. The reality of ground troops being lost and sacrifices having to be made are jarring.

And of course Greg Tremblay was spectactular on audio.

Another good read in the fight to save humanity, but the fight doesn’t end here. A good read start to finish.
