Fantasy book with clear or translucent glass-like sword and female pov character. Very thick book. Read 2008-2014.

If my memory is correct it begins with a younger female protagonist in a remote area who wants to explore the outside world. Cover was a white background with some sort of blue art but I'm not sure. One of the specific details I can remember is the clear glass like sword. Male character and female character found the sword in a small cave or treasury. The other specific moment I remember was the female lead thinking about her destiny or importance as she is going through a burnt or destroyed city. It was a very thick book and I read it some time between 2008-2014.

A lot of these elements can be found in the 4 books of the Song of the Lioness quartet by Tamora Pierce.
