One idea could be to get her a collectors or special edition of the Les Misérables book, either in hardcover or softcover, with a personalized message to her on the cover page to make it more special.
You could also buy her tickets to see the Les Misérables musical show in a nearby city, along with a romantic dinner for the two of you before or after the show.
If your wife is a jewelry lover, you could get her a Les Misérables inspired necklace or bracelet. Several designers offer beautiful pieces with charms that represent the musical or the storyline.
Finally, you could also set up a movie night at home and watch the Les Misérables movie together along with some of her favorite snacks and a bottle of her favorite wine.
Or you can get her a star map with the date of your first kiss.
