Dragon Speaker by Elana Mugdan
Born into a world of magic wielders without any powers of her own, Keriya Nameless isn't exactly hero material, yet the goddess Shivnath chooses her to save the world's last living dragon. She doesn't know why it happened, and frankly she doesn't care-this is her chance to prove her worth. Unfortunately for Keriya, countless others are determined to get their hands on that dragon-everyone from smugglers to kings, from the Empress of Allentria to the most powerful warlord who ever lived. It would be a perilous task for even the bravest of heroes, let alone a naive 14-year-old-girl, and as Shivnath's chosen dragon speaker, Keriya quickly learns that she's at the centre of an age-old war ...a war that will decide the fate of everything.
