Any time I put out a new book, I’m a little hesitant to learn what people think of it, especially reviewers for whom I have a lot of respect. So it’s nice to know that the reviews on MJ-12: Endgame are pretty darn solid.
Note: Some of these reviews contain mild spoilers. Just saying.
Paul Weimer over at Skiffy & Fanty:
Fortunately, as in the vast majority of the first two novels, it is what is going on this side of the Vortex, the lives and problems and challenges of the Variants, and the exploration and investigation of the Cold War and its consequences and hidden facets, that make this story, this novel, this series sing. I come away from this series, which ends here, educated, entertained and enthused for what the pen of the author will bring next.
To be fair, Paul wasn’t super enthused about how the origins of the vortex and the Variants’ powers played out, and you know what? That’s perfectly awesome. Heck, he makes some great points. The fact that he’s looking forward to the next work is very much an honor, exactly because Paul’s discerning and is probably one of the most knowledgeable and widely-read reviewers in the genre today.
Here’s Michael Cook at Thoroughly Modern Reviewer:
Martinez has a gift for these kinds of stories. He has a gift for creating diverse, fully formed characters with captivating backstories. He has a gift for building compelling universes that readers want to spend time in. And he has a gift for crafting interesting, well-paced narratives. His stories are able to appeal to a number of people. This is a spy novel, a superhero novel, an action/adventure novel, and a political drama. He writes for such a broad audience and the characters are so varied and diverse that it’s easy for a reader to find someone in the story they can identify with. MJ-12: Endgame is just a really good time and a really good way to end this series.
I really can’t add anything to that one other than some blushing. Thanks, Michael.
And finally, fellow scribe Luther M. Siler:
My only complaint? I want more, and while Martinez doesn’t exactly tie the universe up with a bow on it the ending makes it clear that while there is definitely space for future books in this universe they will take place in an entirely different status quo. That said, this series is radically different in tone and genre from the Daedalus series, Mike’s previous trilogy, and I genuinely can’t wait to see what he’s got coming next. All available stars; would read again; you should go read now.
Again, nothing much more to add there except my thanks.
Finally, if you or someone you know has read Endgame, or any of my books, I’d deeply appreciate you taking a moment to put your reviews up on Amazon and Goodreads. Those reviews matter. They generate pageviews and put the books in front of more eyeballs, and make more clicks happen, and those clicks can turn into sales now and then. So yeah, you really can help your favorite writers make some bank, and whether it’s my work or someone else’s, please go forth and review!
