im looking buy a book for girl ,

she`s really classy and like old things ,


more about her :

she is a opera vocal , ballerina , and vegan .


i know she like book more than any thing so i want buy her book as a bday gift.

any idea ?

Do not get her a recipe book, she's probably received tons of them from people thinking about what's special about her and her being vegan is the first thing coming to mind. "Let's cook vegan together" is also really lame and common, as a sidenote. She's probably heard it a thousand times.
In general I'm a little againt books and pro activities, because you can build memories together. Maybe you can take her to a dance show or some art event. I think the best presents are not 'obviously her hobby' but an extension of them: something she likes but didnt know about yet.
