Forgotten Heroes #1
The Sheriff and The Space Marine
The final Forgotten Universe series!
When Sheriff Hayden Duke steps through a portal hunting the mysterious arms dealer known as the Marquise, he quickly realizes he just voluntarily entered Hell.
Trapped in a deadly maze with Space Marine Caleb Card, they’ll need to rely on all of their individual strengths—and each other—if they want to survive. Demons stalk the corridors. Shifting walls hide deadly secrets. And somewhere in the darkness, a powerful enemy plays a game where the stakes are higher than anyone realizes.
The legendary lawman who never gives up and the marine with the unbreakable will must lead an unlikely team through trials that have claimed countless lives before them. But in a place where reality itself can't be trusted, even legends can be broken.
Some battles are fought with guns. Others require something more.

The Sheriff and the Space Marine
by M.R. Forbes
I will have to read the rest of the Sheriff books to really get into this. It was great without reading the whole Sheriff series first but I think it would be best to finish it first. By then, maybe the author will have more in this series out.
Lots of action and suspense mixed with sci-fi and creatures. Fast action and interesting characters. Forbes rarely disappoints.

The Beginning of the End
This wild roller coaster of a ride with the Sheriff has been a blast for years, but now it's time to come to an end. Like every entry in the Forgotten universe, I can't wait to start it and race to the finish, only to be begging for more. Hayden is hands down my favorite character since Aragorn. It's bittersweet to see the end coming. But at least Hayden has Caleb with him. When those two team up, it's always an awesome adventure. Although they're trapped in a horrific maze, surrounded by danger at every turn, the duo never stop and never give up. I can't wait for book 2!

Another very good story about The Sheriff and some old friends
Good story, stands on it's own, but it helps if you've r
ead a few novels about The Sheriff. I bought the whole series and I've already started Book 2.
If you like sci-fi, you'll like this.

For all the previous stories, this barely lets you breathe!
Caleb, Ishek and the Sheriff are pulled together once again along with a motley cast of characters to try for survival once again!

One of my favorite series!
I love the Sheriff so much! Thank you for continuing his adventures! I also adore Gant in this book and hopefully we will see more of him.

The Sheriff is one of my favorite things. New twist with this series then add in Caleb Card for non stop action!
