One idea could be to get her/him a special edition of The Bell Jar or a collection of Plath's poetry. Another option could be to create a personalized journal with quotes and passages from Plath's works as inspiration. You could also consider getting Plath's biography "Mad Girl's Love Song" or a book of critical essays examining her work. If your friend enjoys crafting, you could gift them with Plath-inspired cross-stitch or embroidery patterns. Finally, you could consider taking your friend to a poetry reading or event featuring works similar to Plath's style.
Or you can get her/him a star map with an important date you share.
