Merlin's Chosen Book 1 Rise of the Wyvern

Merlin's Chosen, #1

Chandra Strandon has just had her seventeenth birthday and she must now contend with the fact that she moved to a cave in the midst of the Grand Canyon, a clan of dragons, and the fate of the world resting on her shoulders. Oh, and she's also found out she's a sorceress, perhaps the most powerful sorcerer ever to be born and the answer to a prophecy foretold by Merlin long ago. Chandra may be the only hope left to save the last of the dragons from their enemies known as the wyvern. Horrid, nasty, beasts bent on ruling the world, led by the evil Theryn.

As if Chandra doesn't have enough to deal with, working for the wyvern, is Chase Ivers. A boy, who is not only good looking, makes her heart go pitter-patter, but tries to kill her every time they meet. What's a girl to do?
