Kira’s nemeses are back, and they’re after her home.

Captain Kira Elsar is adjusting to her new Robus abilities, but a series of strange attacks on the Tararian Guard’s computer network throw her life into chaos.

A planet-sized ship appears out of nowhere, and it’s heading straight for Kira’s home system. With the lives of everyone in the Elvar Trinary—and Taran Empire—at stake, Kira embarks on a daring mission to stop the massive ship before it can attack.

Conventional weapons aren’t enough to take down the alien vessel. Kira alone has the necessary abilities to defeat the Trols. This time it may be a one-way mission.

Endgame is the fourth installment in the Mindspace series, a space opera set in the Cadicle universe—perfect for fans of sci-fi with superhuman abilities, political intrigue, military action, and devious aliens. Finish the adventure today!

This is more a rant than a review.. I do not understand why some reviewers have to tell the story on the book, instead of giving a honest review of the quality of the writing and / or how engaging the writer is in his/her own style.
Most people do not want to know if the hero does 20 meter high jumps and id impervious to EM pulse. That is not the intent of a review, at least not in my understanding.
What (I believe) most people want to know is if the book moves at a good pace, if the writer makes or not mistakes using the metric system (saying that a 3 mt by 4 mt is a small room, or that it is huge for instance), or if the plot is engaging and satisfying.
Please, reviewers, keep the 'spoilers' out of your reviews.. Just say why you like it or hate it.

Now my review.. This series moves at a very decent pace, I love that each installment on itself is a good story and that the next book on the series builds on it, not on a cliffhanger left on the previous book.. I hate it, really hate it when writers do that, people cliffhanger are chapter separators, not book endings.

A. K. Duboff does a great job building on the Cadicle Universe, but if you have not read the original series, does not matter, you can still enjoy this series very much, that is the signature of a great writer.

Kira faces an even bigger challenge as a planet size ship arrives to use her section of space as building materials. While she has faced challenges before this one is more dangerous than all the others put together. While the challenge was large I found the story around it to be less exciting. There is additional world building and backstory but the presentation slowed the plot to a stand still. There was a final resolution to the aliens and Kira got information she needed about her upgrades. It was a nice ending to the four part series. It is not the last time to see Kira and friends. They will be back in a new series.

Brava!

Another Great Read by DuBoff. I'm loving the Cadicle series and the way it ties into the MD Cooper world of Aeon 14. We even actually see Jason come together with Kira in this book. If you love a good long series that could continue forever, this is one to savor. Try it, you'll like it.

Great sci fi adventure

I enjoyed the Mindspace series. Kira's adventures are an excellent escape from reality with touches of humor and romance to balance the thrills and action. The supporting cast of characters are likeable and important to the enjoyment of the stories. The world building is fascinating.

Mind blowing!

Kira truly comes into her own, and her team grows with her. The Trols are back, and it takes everything from everyone to beat them. This is a fantastic ending to an amazing series, and I can’t wait for the Taran Empire Saga to be published.

Fun read from start to finish.

Pissed off teenagers? Easy reading when the likable characters lead you down a winding, changing path. . . . .
