The Last Colony

Part 3 of the John Scalzi Old Man's War series carries the torch quite well, delivering a good story, advancing/developing the characters we meet and ones we've come to enjoy in the previous 2 books.

Very briefly, this is a continuation of the story with John Perry and Jane Sagan as the primary protagonists. They've settled down as colonists on a human planet when the United Defense Force comes calling. Along the way, they are tricked and cornered. Scalzi continues his excellent way of telling stories, infusing suspense, action, and humor while producing a story that ends up feeling satisfyingly deep and nuanced.

If you haven't read any of these, definitely start with Old Man's War (which is first in the series) before moving on to The Ghost Brigades prior to picking up this one. Those are both 5-star reads, so it's worth the time and effort. This is a good series to invest your time.
