Points of Impact

Perhaps some mild spoilers for previous books.

The previous book was pretty much non-stop action in the battle of Mars. This one, however, is slower paced. Our heroes get reassigned and spend some time training on new weapons and learning new systems and tactics. Andrew and Halley even get a little badly needed personal time. That cannot last of course. Eventually, all hell breaks loose with an all-out Lanky attack on the Formahault System.
In this book, humans have made some progress in learning how to fight the Lankies. But, we still learn nothing about the Lanky history, motivation, biology, economy, etc. Nada. Presumably someone is working on such things, but it seems Andrew isn't in the need-to-know loop.
Perhaps a little weaker than some of the earlier books, but still a solid read. 3.5 stars rounded up.
