To Sleep in a Sea of Stars

I read this book because a friend recommended it to me, even though I am not super into si-fy. I am so glad she did recommend this book, because I absolutely loved it! The world-building, characters, and technology described throughout was incredibly detailed and very interesting. To Sleep in a Sea of Stars is completely unlike anything I've ever read, and it has earned a spot in my favorites!
(Ari, you're the best for recommending this book!)
