How about a subscription to a virtual book club that matches his interests? There are many popular virtual book clubs like Oprah's Book Club, Reese Witherspoon's book club, and more. You can look into these clubs and see which one fits his interests the best. Additionally, you can pair the subscription with a cozy reading lamp and a set of special bookends to make his reading experience even more enjoyable. Another great idea would be to create a custom bookshelf for him to display all the books he reads in his virtual book club. This would be a great way for him to show off his reading achievements and give him a place to store all of his new books.
Or you can get him a star map with the date of your anniversary.
