Michael Simon is quickly becoming one of my favorite up-and-coming Sci-Fi authors. After finishing Fourth Wave, I am even more convinced that he’s one to keep an eye on. Continuing the saga of Earth’s battle against the ‘take no prisoners’ Coven empire, the characters are wonderfully written, and the action is virtually non-stop. And though it’s the fourth installment in the series, this book could be read out of order and still stand on its own. But why not enjoy the entire ride? I highly recommend that you start from the beginning and enjoy the growth of Captain Cole Jackson and his intrepid crew. Drama, action, and humor are interlaced throughout. A fun and fast read, and it seems there’s more to come. Can’t wait.

Mediocre

While I’m still enjoying the storyline, there are so many annoying things that bring the quality down.
Is it a fleet, or an army? It’s a goofy mix of army and naval ranks that doesn’t make any sense.
The haphazard melange of British and American colloquialisms is confusing. It’s very lazy writing. I’ve never been relieved to see that the release of a next installment in a series is so far away. Until this one. By then, hopefully, I will have forgotten how poorly written this really is.

Three and a half stars actually.

The physics in this series has been dicey at the best, stretching your suspension of disbelief to its limit. But in this installment, at times, Simon has made it a shortcut for some lazy writing. Secondly at the end there was one highly implausible and stupid plotline that ran contrary to the character of the MC. Now that is inexcusable.

Otherwise a solid book with an excellent plot, immersive action and decent writing.

Good

I enjoyed the first four books. I would recommend them. I do have to say, that the author obviously has no idea about how the military works. It was frustrating at times to read some of the things he wrote that were so unlike any military. So you have to just grit your teeth and ignore it.

Into the breach

Oddly joyful for the amount of loss. It's always good when the villain meets the hero in the end up in a place where the hero seems to have won. But because they left it open for so many sequels you know it didn't really finish.

Opinions

I have read the first four of this series thAt very much enjoyed them all. They are a mixture of humor and space opera that's very well done.

Quite an adventure with unusual improvisations. Plenty of action.

Another great addition to the series!

This author always keeps me on my toes and delivers a solid story with great characters and excellent tension. Can’t wait for the next book!
