Technically it has nothing else to do with Shakespeare, but I'm just about finished reading Old Man's War by John Scalzi, and enjoying it very much. It's somewhat of a classic scifi story, "the universe needs troops for its interstellar army" and all that sort of thing. Been done in many ways over the years.
Why I'm posting, though, is the scene in the middle where a bunch of the old Earth folk, freaking out about having been in space so long, compare notes on what they miss the most. One of them misses Shakespeare in the Park the most. Later, we learn that the narrator has an even deeper back story with Shakespeare.
I wouldn't recommend the book based on that, it's not like Shakespeare is essential in any way to the plot or the characters. But if you like that military scifi stuff, I'm just saying, this one's got some Shakespeare in it.
