A great gift idea for your boyfriend who likes Stephen King would be to get him one of Stephen King's latest books, such as "The Institute" or "If It Bleeds", or a collector's edition of one of his favorite books. You could also consider getting him a signed copy of one of King's books, which can be found on websites like eBay or through collector's bookstores. Another idea would be to get him a Stephen King-inspired gift, such as a t-shirt or mug with a quote from one of his books, or a set of King-inspired bookends for his bookshelf.
Or you can get him a star map with the date when he was born.
