Summary:
The Sarge's brother is missing. The team of bad-ass mechs are going off the books to find him. Lots of action, big bangs and some gruesome injuries. It's not just a fetch quest, it's an epic journey

Pros:
The action is well written. I could taste the dust and grit, the anxiety, the desperation and general bad-assery. If you like big mechs, AI and scifi-ery this scratches the itch. The world building is fun and really got my imagination going. The protagonist is hard as nails but shows some vulnerability as well.

Cons:
Some parts feel a bit predictable. There's a lull about a third into the book. Get over it and two twists will get you going again. I had to re-read some parts I didnt quite get, but that could be because I'm not a native speaker.

My 10 cents:
I liked it. I lost about two hours of sleep finishing it. I recommend the Scavenger by the same author. That made me read this. Preferred Scavenger, but this was good too. I know more about the factions and world now. Might dip into the series again later in the year.

Thanks Scott Moon. Really cool, I had fun.

Difficult to read

I only made it 33% through the book. The writing was really hard to follow and I had to reread sections several times. The book is written in 1st person narration. It's in the perspective of Jam. It's his thoughts about what is going on. The narrative makes a lot of absolute statements about what he thinks happened. It's stated it a way that makes me think it's a fact. But shortly after these "facts" are stated the reverse ends up happening. Maybe he's being sarcastic a lot and I just can't seem to catch it. Also the dialogue between the characters is very realistic with a lot of inside jokes or phrases that aren't always explained. Lastly the story pace is very quick with time jumps in the middle of a page. This would be fine if everything else wasn't already hard to follow. I do really like the characters and the world I just find this book hard to read and relax while I'm reading

A Gripping Start to an Unforgettable Journey

The first installment of the Tall Boys Trilogy is an absolute triumph, pulling you into a world that’s as thrilling as it is richly crafted. The plot hums with energy, weaving twists and turns that keep you hooked without ever feeling contrived. The characters leap off the page, each one distinct and brimming with personality—none more so than Jam, whose razor-sharp attitude injects every scene with a mix of grit, humor, and heart. It’s the kind of book that doesn’t just entertain; it lingers, leaving you eager to dive into the next chapter of this epic saga. A must-read for anyone craving a story that’s bold, smart, and utterly addictive!

Picked this up from a Facebook ad and 100% don't regret it. Solid military action throughout, with likeable and interesting characters (humans and AI alike).

I'm sure it was advertised to me because I'm a Battletech fan, and if you also are, I think t think this will work well for you (similarly if you're a fan of Titanfall, or Heavy Gear, or the original Starship Troopers novel.)

Lots of enjoyable twists and turns!

Lots of clever banter and good opposing character development. Scott Moon is way smarter than me, and I wonder if I really get all the twists in the story. It's like being led through a maze, but a maze that you can't stop in because the next corner is so alluring. It was an entertaining read, especially if you like companion exoskeleton war machines with Artificial intelligence like I do.
Good job!

only got about 10-15% in before I had enough of the writing. moon wrote something to the extent of "she was 30, unlike the rest of us" but then did not mention everyone else's age. they see enemies straight ahead but the enemies don't notice 7 ton mechs stomping around. they let themselves get encircled by the bad guys that didn't know they were there... wtf?

I might have eventually liked this, but I wasn't drawn in fast enough

Couldn't put it down. Epic.

I first got a taste of this universe and characters with the short Salvager novela, which was more or less a prequel. The world building, storyline, and characters are top-notch. This was a fresh take on the Military Sci Fi mech warrior genre. This was a real page turner. I can't wait for the next one

Enjoyable, but stilted and needs polishing

First off, I’m interested in reading more of this series and it’s engaging. But typos/errors, choppy prose, and stilted dialog makes this a bit of a chore to read. Hopefully the later books improve (and I’m willing to give them a shot) but there are parts here that feel more like an outline rather than a finished product.

It's an interesting story, it scratches that sci-fi itch, and isn't too full of itself. The belief one need provide it isn't a stretch, seems like a plausible future, the aliens feel a bit monodirectional; however, it seems we tend to write about races as unified, or aligned, where the human condition is anything but that.

Brace yourself for some serious action in a big tin can!

This book moves fast. Action, mischief, trouble, and adventure at every step. Written and spoken like someone who has been there. I look forward to the next book.

Another home run for Scott Moon

Gripping and well paced. The characters are well thought and fleshed out. I finished reading far past my bedtime, I was not willing to put this book down.

Good read.

This book was a good read . I thought there would be more fighting in it but instead they made a new ally and found out about a bigger war going on headed there way with bigger machines and a lot bigger people instead of just the three wars going on on this planet.

Very good reading, and different too!

Great science fiction, great action, and different than most books of the genre, I really recommend this one to all fans of military science fiction with a twist. Oh, and lots of humor too.

Great Start! Already bought the next 2 in series

Great character development, troop attitudes and interactions ring true. Mission goals fluid, lots going on, new friends(?) bring news of greater enemy. The stage is set, Tall Boys will be ready.

Lots of things to complain about. Written in the first person (choppy, blunt prose), and what it lacks in context and descriptions it tries to make up for with nonstop action. More than a few grammatical errors. And an end that reveals it’s just a setup for the rest of the series.

Great!

This is a fun read! It's what I've come to expect from Scott Moon. It's got great characters without too much world and character building. As a fan of Moon, Chaney, and McGinnis, I would definitely recommend it

Oh my!

This never slowed down nor got stale. It likely has been many decades since I read as good a SF book

Great combat story

Lots of action, world building without chapters of exposition, and characters who react from their own motives and even grow a little in the process.

Good read. Want more.

Good read. Good comradery. Action could be more, some things took too long. Good main character, funny, brave. Try it yourself.

Love the premise and plot is nice to follow. Combat scenes are a bit messy, some being hard to follow and some non-sensical as the way they are described would be impossible based on what was going on. One enemy group got deleted after one of their attacks, as in, they were just gone, with no explanation. Overall not bad, just a few things that made this less enjoyable than others.
