One idea could be to get him a collection of Dostoevsky's works, such as "The Brothers Karamazov", "Crime and Punishment", and "Notes from Underground", or a special edition of his favorite book. You could also consider getting him a biography of the author or a book about the impact of Dostoevsky's writing on literature and philosophy. For a more unique gift, you could look for a first edition or signed copy of one of Dostoevsky's books, or a piece of art that references his work. Additionally, if your boyfriend is into coffee or tea, you could get him a mug with a quote from one of Dostoevsky's books, or a gift card to a local bookstore where he can explore more works by the author.
Or you can get him a star map with an important date you share.
