Agent to the Stars

Ted Chiang's Stories of Your Life and Others is the best, single-author collection of short stories I've ever read. If you like that, you might also enjoy The Lifecycle of Software Objects, an absolutely heartbreaking novella about simulated children, and his follow-up collection Exhalation. Orson Scott Card's Ender's Game is fantastic, and it's follow-up, Speaker for the Dead is even better, and my favorite science fiction novel of all time. They won back to back Hugo and Nebula awards. Card is a polarizing figure for his outspoken political opinions, but if ever the art should be separated from the artist, it's Speaker, which is an incredible exploration of empathy and responsibility, in addition to being a gripping, action-packed, science-literate read. Many more in this series, if you get into it.…

I'd highly recommend any Scalzi book. The Old Man's War trilogy is great, but if you're after something more light-hearted then The Android's Dream or Agent to the Stars are also great.
