The Last Colony is the sequel to John Scalzi’s Old Man’s War and The Ghost Brigades. It continues the life of John Perry (from Old Man’s War) and Jane (from The Ghost Brigades), along with their daughter Zoe, as they go to administer Humanity’s newest (and quite possibly last) colony, Roanoke. For those who aren’t as well read up on history, the original Roanoke colony disappeared shortly after founding, with none of them ever seen again. Luckily for our protagonists, that isn’t quite the fate that awaits them. Rather, the organization that the Colonial Union tried to set up against the Conclave has collapsed, and the Conclave has begun a ban on colonization not under it’s own auspices.
Since this book focuses more on their life as civilians, much less action is seen compared to the previous two books. However, there is still some (the biggest of which is the destruction of a fleet of over 400 ships). If you like the previous two books in the series, you’ll probably like this one, though you’ll have to wait a while for the fourth.
