Thanks to my twelfth grade English teacher, not only have I read and enjoyed Hamlet, I can point out every single sexual reference in the entire book. (Also, when we watched a movie version, she paused the tape at this point when some jesters were doing flips so we could see up their costumes!) We also read Rosencrantz and Guildenstern are Dead (which I highly recommend), so I was very interested to see what Lisa Klein would do with the story of Ophelia.
Klein's interpretation is definitely not the traditional one -- her Ophelia is a much more dynamic character than one would expect from reading Shakespeare, and some of her other characters were not quite what I expected as well (She writes Rosencrantz and Guildenstern as traitors rather than as simply bumbling fools). However, her interpretation is still completely plausible, and, I would assume, could be backed up by Shakespeare's text.
I'm not going to tell you much about the plot because, if you've read Hamlet, you know the basic plot anyway, and the interesting part is seeing it unfold through Ophelia's eyes, and if I were to tell you how it differs from the traditional Hamlet, I would take all the fun out of it.
I would definitely recommend this for any Shakespeare fans, or simply to fans of historical fiction (the novel can still be enjoyed without having read Hamlet). Klein's intricate story-telling kept me enthralled, and I can't wait to see what she will write next (Might I suggest something based on Romeo and Juliet?)
