Looking for an Author/book series, female author fantasy


First post! Greetings.

I am wondering if anyone can help, I am looking for a series that I started reading around the early to mid 200's, the author is female and it's a series where magic significantly uses up the years of someone's life.

Everyone is sparing using the magic as a result. I thought the authors name was Cecilia but I think that's wrong.

I read the first 2 books and I was waiting for the 3rd I think when I forgot who she was!

It mustn't have been a really common set of books. I think that some characters could turn into birds, not sure.

Any help appreciated!

It sounds like the Magister trilogy by C.S. Friedman (a woman whose first name is Cecelia or something of that nature).
