    The Martian by Andy Weir - I’m half-way through the audiobook and it’s a great, action-packed story. The author obviously took great pains to make it realistic and explain the physics, chemistry, botany, etc relevant to the plot.

    Note - I’m usually indifferent between text and audio versions, but the narrator for this book does an amazing job, so I’d go for that version if you’re on the fence.
