title of a 50year old book about a girl name starts and ends with A

Dear all,

A pretty romantic question, but a girl (28) I have been writing now for quite some time, has given me a clue to her name,(its a game, we use pseudonyms) she is Polish and she says her father new he wanted her to have the name of a teenage book character (girl) when he was 13, its also the title of the book. The name starts and ends with an A, and she maintains it is unpronouncable by anyone not Polish.

Thanks for any clues tips or advice.

I was going to suggest Anastasia (english spelling) but I don't think only Polish people can pronounce it. Sorry I can't help you.

Agnieszka.
There is a book by that title and it is hard to pronounce to non-Polish.

Thank you soooo much, I am just dropping her a supportive note about some emotionally delicate news she shared earlier, and you have sent me a lovely gift in being able to do this. I am so greatfull, God bless.

You welcome. Let me know if that was her name.
