I loved Dark Matter, Crouch’s award-winning science fiction novel based on the notion of parallel universes. When I was invited by Net Galley and Random House Ballantine to read and review Upgrade, I jumped on it.

This is a story that hits the ground running. Logan is a scientist, and he’s also a husband and father. He leaves home one day in the normal fashion, and he never gets to go back home. He’s been kidnapped, more or less, by his own government; they plan to use him in experiments, but then he’s busted out of there by a badass ninja type that turns out to be his sister.

Surprise!

The pacing is swift and at times, the story is electrifying. However, the first half of the book is more interesting than the second half. My main criticism is the unhappy appearance of one of my least favorite tropes, the Bad Mommy. How has any living author missed the fact that this device has been done to death? Without this annoying feature, I would rate this book 4 to 4.5 stars.

As always when I read science fiction, I cannot tell you whether the science aspect of this novel is credible or entirely made up. I am a humanities animal through and through, so with every scientific explanation of a development in the plot, I just nod along. Okay. I believe that. Of course, I’d believe anything when it comes to scientific explanations. I have no idea how much is actual science, and how much is pseudo-, and I am okay with that. After all, it’s also fiction.

Crouch’s fans will likely appreciate this novel, and those without my own aversion to the trope mentioned above may very well like it, too. It’s for sale now.
