I don't think it's ever taken me more than two days to read this book, and I've read it several times now. It's just that gripping. You get to the point where you stop lying to yourself about "just one more chapter," and decide you'll live with the sleep deprivation. Watney is the kind of guy the whole internet wants to be, in a situation that nobody wants to be in. Yet the bottom-line struggle—things keep going wrong and nothing is cutting him any slack on Mars—is totally relatable and understanding.

What an impressive book. If Weir's timeline is right, the first astronauts to go to Mars are in high school right now. I hope they read this book. And then I hope they push past the new fears and complexes this book will give them and go to Mars anyway.
