One idea could be to get her a first edition or special edition of Sylvia Plath's book, "The Bell Jar". This will show that you have been paying attention to her interests and that you are supportive of her passions. Alternatively, you could put together a DIY Sylvia Plath inspired gift basket, including items such as a copy of "The Bell Jar," a Sylvia Plath quote or poem print, some of her favorite teas or coffee, a cozy blanket, and some scented candles. This will show her that you value her interests and have put thought into creating a personalized gift for her.
Or you can get her a star map with the date of your anniversary.
