Cara and Silverthief

"Cara has always had a little voice inside her head that's helped her out of danger. When that voice turns out to be a dragon, Cara's world is turned upside-down! Suddenly, she and Silverthief are part of a secret guild of Dragonseers--a select few who can see dragons and together protect their kingdom from enemies. But Silverthief is suspicious. Is the Guild really that perfect? Or are some things just too good to be true?"--Amazon.
