Book Log 2019 #44: The Ghost Brigades by John Scalzi

The sequel to Old Man's War, it introduces us to the Ghost Brigades, the special forces units of the Colonial Defense Forces. Where their regular troops are elderly, living people who get their mind transplanted into young, new, enhanced bodies, the Ghost Brigades are created from the DNA of dead people, and optimized for combat. 

I won't go into too many plot details to avoid spoilers, but suffice it to say that creating new beings out of DNA doesn't always go as planned. 

Kind of funny that I read this after The Obelisk Gate, as they're complete opposites in many ways, but they both excel at the sort of reading experience they're aimed at giving, so maybe it's not that odd?
