I liked that this third book in the series takes us back to the protagonist of Old Man's War (John Perry) and characters from the second book (Jane Sagan and Zoe). We follow the characters in the process of starting a new colony in another planet: Roanoke. I think John Perry has always been my favourite character because of his human traits. I missed some more development about the race inhabiting the planet: it seems it could develop into a main plot issue, but it's totally forgotten at some point. There are some interesting discussions about the costs of war, colonization rights and genocide in the name of peace. These themes are never explored too deeply, making it a light read overall.
