I think The Martian would be a great place for you to start. It's not too long, the plot is interesting but still relatively simple, and it's entirely self contained. It does assume a degree of intelligence from the reader (it's littered with engineering terminology and the like), but it's always done in a way that even when you don't fully understand the science behind something mentioned, you understand the end result and its importance to the plot.
Adding to all that, it's not one of those "you need to keep reading to get into it" books. You'll know within a few chapters if you're going to enjoy it or not.
