Void Spheres

Aether Spheres #2

by Glynn Stewart

A ship unlike any other, forged to travel beyond the spheres
A journey into darkness, among spheres long since dead
A weapon that should never have lived—and once forged, cannot die…

When he heeded the call of a powerful archmage and hired the only crew desperate enough to follow him into the void, disgraced elvar captain Cat Greentrees didn’t realize that it would turn his worldview on its head. Widely reviled and viewed as criminals, his new crew of gobvar—an entire small clan led by a young shaman—quickly proved itself the equal to any crew Cat led in the navy.

Now, to evade a prophecy that could threaten all of the var, Cat and his archmage had stolen a strange ship that has allowed them to enter the ruined spheres of a long-dead empire, spheres whose lack of air, aether, or life stabs into Cat’s very soul.

The ruins around them hold the supplies and perhaps the answers they need to complete their journey, but these broken worlds are far from safe. Because once, the Blood King of the Gobvar ruled these halls. The old stones themselves share a mind... a mind still loyal to a King that should be dead.

This was a great book, minus the cringy romance. I know it was a successful kickstarter, so the author got some money in advance that validated it as a commercial success, but I am a bit miffed at how many things happen in this book while I feel that my favorite series, Starship Mage, is limping along from book to book in by the numbers sequels. I really appreciate how the author creates hooks for worldbuildings. This one is especially creative, mixing high fantasy, Treasure Planet, pirates, steampunk and more.

The story was very good and moved at a good pace. There is a good amount of action and a lot more character development. The story brings us more into an Epic Fantasy or Swords and Sorcery plot line. It was very enjoyable as the author has a knack of excellent story development. With additional recruits at the end of the book, I look forward to see where that will take us. The author has another winner with this book.

Always Exciting

Stewart writes Visionary Fantasy/SciFi like no one else currently working. All of his books deliver story & character in entertaining & unexpected ways. The plots may, in the end, seem straightforward but there’s always a twist.

I look forward to the third volume

You should already know the Author is an excellent story teller. And he has produced a lovely and complex plot.
And that is just the first two books.

Don't read this first. The first book sets this one up.

Enjoy

I like when an author tries to play with physics and does a pretty good job of it. Glenn Stewart did that with the Mage series and has done it again in a totally different fashion with the Void Spheres series. I am looking forward to the 3rd book.
