Looking for a book with a female character with unusually dark eyes and hair in a desert setting.
The girl also an orphan, and she can speak any language she'd ever heard (Arabic, Turkish and French mentioned). She remembers from her early childhood her native language, but no one she ever asked about it can identify it, and she doesn't know the name of the language herself.
She lives in the slums and uses her medical diagnostic skills to cure people, but passes it off as magic in which she herself doesn't believe. The reason for her act that it is illegal, or at least frowned upon for women to be healers. In one of her magic sessions with a 'possessed' girl, she decides to use her native language, to impress her clients by making the incarnation more mysterious, but accidentally summons an ifrit or a djinn.
The MC's name starts with an N, no family name.
I heard about the book in YouTube book recommendations now I can't find.
