The Vanished Birds

A story about a farming colony that receives a spaceship every 15 years that comes and picks up their produce. Due to the effects of space travel, those on the ship don't see that much time pass in comparison, so each time they return to the planet the people there have aged significantly, which I thought was a pretty neat plot point. Overall it has quite a bittersweet tone but I really enjoyed it! Could be my new favourite sci-fi book.
