Nnedi Okorafor is one of my favorite authors! I especially was fond of her book Zarah the Windseeker as a kid.

And oh my goodness, if you're reading a Finnish YA book that I've been looking for for years it'll be such a coincidence. Is it about a kid whose grandmother is teaching her Finnish spells? I've been looking for the name of that book for years. I read it as a kid and have been on the hunt for it for awhile.
