How about a set of first edition Harry Potter books signed by J.K Rowling? Or, you could get tickets to The Wizarding World of Harry Potter theme park and plan a weekend getaway to experience it together. Another idea would be to create a Harry Potter-themed gift basket with items like a wand, house robe, butterbeer mug, and other memorabilia. Finally, you could plan a surprise trip to London to visit the locations where the Harry Potter movies were filmed, such as Platform 9 3/4 at King's Cross Station, the Harry Potter Studio Tour, and Leadenhall Market (the inspiration for Diagon Alley).
Or you can get him a star map with the date of your anniversary.
