Echo Flight: Graduation Day Book 3

Rate this book
The Horizon has barely caught its breath when new orders send it beyond the edge of known space. Intelligence has traced alien technology to its source. What they find is not a ruin. It is not abandoned. And it does not intend to let them leave.

Tara Holt is the only person who can understand the technology bonded to their ship. But it is changing her, quietly and relentlessly. She is their greatest asset. She may also be running out of time.

Far away, an intelligence officer follows a thread connecting a terrorist attack to some of the most powerful people in the Alliance. The trail leads to the Granger Institute, a luxury resort that wears respectability like a mask.

Behind it, criminals set the rules. Strangers who ask the wrong questions disappear.

He has barely stepped through the door before someone tries to make sure he never steps back out.

THE HORIZON & HER CREW SET OFF FOR AN ARCHAEOLOGICAL SITE TO GET ANSWERS TO WHY THEY'RE AT WAR

5/07/26 Review:
⭐⭐⭐⭐1/2


Echo Flight: Graduation Day book 3 by John Walker is another addition to a very good sci-fi military thriller that will keep you on your toes while the crew of the Horizon head out for their third mission, this time, into the Velaran territory to get answers at archaeological dig site that seems to be the cause or at least a place to start to look for the reasons the Alliance is currently at war. The characters are well written and you'll find yourself at the edge of your seat trying to find out just how they are going to make it out alive with the situations they are thrown into.

In the previous book, John introduced us to Cole Bradt as a new member of Mason's team working as an intelligence officer tracking down who were responsible for all the lives lost on Hamish's Point and to find answers to the alien technology that they were studying. Cole finds himself in deep shit at the luxury resort at Granger Institute trying to track down the man responsible for the loss of lives at Hamish Point and bring him in for questioning. What Cole thought would be an easy job turns into everything but easy.

All along, the young crew of the Horizon find themselves knee deep in trouble on what they thought would be an abandoned archaeological site in enemy territory faced with alien technology that is very much still active and very deadly. Elias, Nora, Rafe, Tanner, Rebecca, Tara, Tanner, Tresa and the rest of the crew of the Horizon have their hands full trying to escape the clutches of the ancient Velaran technology that is doing everything within the power to destroy the Horizon and her crew.

At times this third book in this series is fast paced and full of action and humor but at other times it felt a little lacking in the action, therefore, I had a hard time giving this third book a full five star rating. That being said, this is still a very good military sci-fi and well worth the time spent to read it and I truly look forward to the fourth addition to this series that hopefully will be released soon.

The series is not worth it.
Too many plot holes, incompetent pacing (when are watches relieved) shallow characters (who are getting shallower per book) and lazy dialog.
.
This just isn't a well written novel or series. The author needs to take a few creative writing classes. To be honest, this is so badly done I suspect it's an AI generated book.

Do not buy.

All in all a good read

Well folks this is a tough one. The plot and characterwise, the book was great. I kept getting hung up on syntax and word choice that messed up the prose. Some of the "science" or tech was clumsy in places. The crazed scientist being assimilated by the alien drones taking his body apart and somehow allowing his mind and thinking ability to survive and become conscious instantly inside the equipment and taking over the alien construct's superior intelligence as well as the planet's near instant destruction made me shake my head in dejection in the finale. The escaping shuttle would have splattered by the somehow increased gravity of the planet while the powerful starship couldn't escape. DARN. A good story until that. Maybe a few first readers? Jess.

A good continuation of a promising seties

The story continues as more secrets are discovered and our team set out to investigate.

The writing seems to be improving as we move into this series. There are a few typos here and there and sometimes the narrative rambles a little but overall, this is an enjoyable and intriguing read..

I'm off to download book 4.

The song continues...

Slow start then ACTION!

Well....Science Fiction has built in everything goes, but this, this is pushing at the upper levels of belief!! Don't get me wrong, great action story, good characters but it pushes the belief scale a little too far! Still, a good story is to be had, just let your action side win out over your physics class education!

I'm intrigued if not the best writing

The writing could honestly use some work. It doesn't really illustrate what's going on and you're kind of letting the characters narrate as they make impulsive decisions while just having an internal monologue about not knowing what to do.

That said, the overall story is interesting to follow and I'll keep reading.

Good story

The writing is weak. The story is good. I like the world for the most part. The author either doesn't know how a ship works for crewing or has chosen to ignore crew shifts. Anyway, I'll continue reading because the story is good enough to forgive the holes.

No longer students or cadets, but warriors!

Elias, Conners, Rafe, Tara, et al are now explorers tasked with finding the answers to the questions of who's response brought them to the edge of the universe!!???

In this episode, there are two separate groups performing in mostly every other chapter, yet while that activity makes sense in the 'series' the activities are not reasonably connected in this book. This is not a standalone story.

Interesting read

Well book 3 gives us some more information, but the twist and turns keep on coming. The biggest surprise is not what you see coming.

good read

Author should take a college level class in English grammar. Actually a decent high school level grammar class would probably suffice. Or, possibly a decent editor.

Excellent

But it was a scanner... Drats... Oh well, I'll be moving on. I gave it 5 stars to honor the work the author put in writing it. 🙂

What's next

Well looking forward to the next book. I love this kind of science fiction. One wonders when these things will become real. Today's fiction becomes tomorrow's reality.

While I don’t like Cliff hanger’s, this one’s got brass. Keeps you engaged until the last page. Must continue 😁

Yep the big cheese shows up to hate the day. Leaves us wondering if anyone understood why she decided to engage them.
