Half-Moon Trench

by Michael Cole

In the Pacific Ocean, three miles deep, lies a deep gorge known as the Half-Moon Trench. It is a place of literal darkness, unknown to most of the world. Now, it is home to an advanced deep-underwater mining facility known as the Scarlett Caldera. Owned by a powerful corporation, it operates with the goal of harvesting the secret to renewable energy.

But now, the Scarlett Caldera has inexplicably gone dark. Computer logs reveal the departure of escape pods, but none arise to the surface; grainy security footage shows staff members fleeing some unseen force within the facility; and all radio contact is gone.

Dispatched by G.O.R.E Sector, Raptor Pack sets out to investigate. Equipped with state-of-the-art exploration technology and combat weapons, Thomas Rodney and his team make the three-mile descent into the trench.

There, they find the station dark, vacant, and deathly quiet. Thin grooves line the bulkheads, bloodstains soak the decks, but no bodies are found. But something moves within the darkness.

Watching.

Waiting.

As the team presses further, they uncover the true purpose of the Scarlett Caldera’s operations, as well as the deadly consequences.

With disaster looming, Raptor Pack must race against time to rescue a small group of survivors and destroy all mutations inside Half-Moon Trench.

Michael Cole GORE Sector series is

...A good story line that just gained a whole new level of adversity. Not just fighting freaks of nature anymore, there is a new element of conflict to drive future stories toward.

...A potential love story with a burgeoning romantic twist ahead. There are some more hints toward a relationship between a couple of the Raptor Pack members. Can't wait to see that play out.

...A reliable "good-ending" tale. The good guys win and the monster gets defeated.

Ready for the next book!

Undersea Mayhem

Half-Moon Trench by Michael Cole is yet another fun addition to the G.O.R.E series. The overall story was really good and flowed well. It has plenty of funny moments in it as well as tense moments. There is plenty of gore and kills by the creatures in this one as well. I enjoyed how there were multiple creatures in this one. Overall I would definitely recommend this to anyone.

using the location for the name wasn’t interesting title

G.O.R.E the last defense in adverting a monster world if big Corps don’t stop them for a bottom line. Only time will tell who will in this series if giant battles

So fun

I love these books. They are like the best OG monster killing fun books ever. I wish they would bake them into movies, we need good monster movies so badly. Fun and gory and cheeky. I wholeheartedly recommend them.

Raptor Pack are back and this time they are heading to the bottom of the ocean, as more mutated monsters appear. Up against a corporate firm, who are trying to keep a secret hidden, it is not only the monsters they have to contend with.

Equal adversaries

As usual the team are well worth keeping track of. Non stop action, impossible odds, and very amusing teammates. I love the series and can't wait for the next event.

fun quick read

A fun quick read that takes us deep into the ocean. Short novel and that gives the reader a glimpse of what is coming up for the team.

Cliche dialogue but fun read overall

This felt like a B movie read. Fun monsters but things happened a bit too easily and the dialogue was pretty cheesy and unbelievable at times.
