"Logos", the final book of the Link trilogy picks up where Pathos left off. Calvin Brooks returns to Ethos where an invasion by the Hiphol is iminent and the capture of the colony is all but guarenteed unless he and his people can come up with a way to persevere against overwhelming odds.

Luke Dalton is in enemy territory attempting to rescue his captive family and return them to the colony on Ethos, unaware that they will likely return to an ongoing battle which may already be lost.
Jane has set off with Henry Abimbola on a mission to discover the true nature of The Link which is crucial to their efforts to save Ethos and Earth from the Hiphol threat. This is just the bigining of all the events that lead to the conclusion of this saga. The old characters are still there and some new ones appear. There are many more surprises and revealations as well.

The story is well-written and each chapter seems to get more compelling throughout the book. Hystad has created a great story packed with interesting and relateable characters and loads of adventure. I recommend any new reader to start with "Ethos" and read the books in sequence to gain the full experience of The Link series.

Great story!

This was a great story! Characters were wonderful, action and flow exhilarating, and it actually has an ending!
However, I find it incredible that someone can be a prolific, bestselling writer, but not have any better command of the English language. Nathan, your grammar sucks and you use words incorrectly (i.e. circumvent instead of circumnavigate), which probably speaks poorly of your readers (me included) for contributing to your success.
Also, apparently you either don’t read your own work, or maybe write in fits and starts. At the end of book two you kill off a character (robot), but start the third book with it still in the cast.
I’ll probably read more of your books as they are entertaining, but I’ll also continue to encourage all self-publishing authors to, at the very least, get an AI to proof read your work before publishing.

❤️🤗Excellent and captivating sequel!

Captain Calvin Brooks was about to give a speech to thousands of soldiers.

Seeing his hesitation, Captain Sanya Levin stepped forward and patted him on the shoulder...

He composed himself and gazed at the colony stretching into the distance...

********

An excellent and totally captivating sequel, a real pleasure to read, and full of unexpected and very well-executed plot twists.

The story is absolutely thrilling to follow.
I still love the characters so much.
This is undoubtedly my favorite of the three books.
Given the ending, I wondered if there would be a sequel...

Highly recommended!

What a great read this book was.  "We are Hiphol" - okay, but who are they?  Everyone comes across this phrase on different planets, and it's never good.  There are the Locus, the clones and many alien beings that are unknown.  Calvin, Jane, Luke and many others try to discover how to defeat their enemies.  The war is on.  This book was fast-paced and a fantastic read.  I love seeing into the mind of Nathan Hystad.  You never know what will come out, but I can guarantee it'll be wonderful. Thank you, Nathan.  Looking forward to the next book in the series.

This is book 3 of The Link series. If you’ve put in the time reading the first 2 books Link series then you’ll get the action and plot when they heat up. This series is a story of growth mixed with danger and mystery. Logos brings the vast cast of characters together in a way that “solves” the storyline. I didn’t figure out the ending like I usually do with books and films. I recommend this book to all readers.

I received an advance review copy for free, and I am leaving this review voluntarily.

Another fantastic addition in this series.

So much happening all at the same time, it's hard to stop reading.

I've really enjoyed these books. Multiple storylines, compelling characters and lots of robots.

This instalment is also a great setup for the next book, so definitely looking forward to that.

Considering everything they have gone through up to now, things get a bit more crazy in this one. Lots of drama, surprises, twists, missing people to find and so much more. Easily grabbed me from the beginning and so hard to put down. Had to see what was going to happen next and what was in story for my characters. Loved it

Hyphol attack

So the inevitable is about to happen and the Hyphol are on their way to enslave humanity like they have done with countless life forms. It’s a race to prepare not only Ethos but Earth and the Sun Colonies as well. Not to mention, can Luke save his wife, Daughter and Henry’s parents from a Hyphol mining camp. The clocks ticking.

A fitting end to the trilogy.

Still had the same issues as the second book, where it's difficult to keep track of what character is where and doing what.

Sorry Mr. Author, none of these characters are likable or memorable.

Book Three helped to tie everything together and ended up with a great ending. During the first two books it was difficult to remember all the names and the characters, however, I was surprised how well the characters and story came together and it all made sense. Great reading!

Science fiction at its best

Good series

I like this author and have enjoyed this series so far.
I'm typing now because 5 more words are required.

Best of the three

So many things happening at the same time. It all comes together in the end. I don’t want to spoil it for you all, but there are surprises.

Reads like a B movie

The last of the trilogy was much better than the first two.

[Juliana · Rating 5 out of 5]

Incredible book that will not let you put it down. Following "Ethos" and "Pathos," "Logos" culminates a stunning story arc. It will be fascinating to read about Logos and ultimately Earth. Each character continues to evolve yet the pivots and entrancing developments are so unexpected! It's a mystery in a science fiction setting. Personal agendas continue to unfold and new ones arise. It is impossible to put "Logos" down. Very addictive.

And in the end it turned into the inevitable and predictable. Intergalatic war. Calvin Brooks became the thing he hated. Such a shame.
