The Martian by Andy Weir.
Mars mission goes afoul, 5/6 crew members escape, but one gets left behind. The story of his attempts to survive and the absolute clusterfuck that ensues when NASA discovers that he's still alive.
Very much based in science. No impulse engines to save him.
This book is on my Wish List. I will be interested in your opinion of it once your have finished.
I am halfway through The Ice Limit
by Douglas Preston and Lincoln Child. A very strange meteorite has been discovered on a subarctic island and a billionaire sends a team to acquire it for his museum. Very interesting so far.
