#FinishedReading one of my absolute favourites as a child when I first got old enough to raid my parents' bookshelves, so a huge nostalgia hit for me in this. This is a classic 70s first contact #SciFi story and fortunately stands up great to re-reading as an adult, apart from the almost total lack of female characters, which I notice these days but I guess didn't concern me as a preteen boy. Still, inventive, surprising, and lots of fun. #Bookstodon@bookstodon#LarryNiven#JerryPournelle
