G.B. Wren

This is the first book in The Silvering Series.

Loran Avileen, the beloved daughter of Gilvius, the sovereign of the Avileen Empire, never believed in magic. That changed on the day an inquisitive stranger found her muddied and hidden in the bushes near the wall of Avileen castle.

Magic isn't the only thing Loran discovered is real. So is the blackened stone worshiper, a vengeful sorcerer who walks the halls of the castle while he secretly changes the course of the Avileen bloodline. He has secured a protégé trusted by her father, and they will not rest until all of the Avileen Empire falls under the rule of dark magic -- and Loran is forced to live a life with a man she doesn't love.

Loran needs the help of a powerful ally in a distant realm, and she only knows one way to reach him. She must master the secret of the silvering with just an ancient magical book to guide her.
