Once Upon a Dragon Wish by Adrienne Woods

Elena Watkins has spent her life moving every few months, never able to stay in one place long enough to call it home. All she wants is a normal life, with friends and stability. That is, until Blake Leaf arrives at Falmouth High. Mysterious, intriguing, and undeniably attractive, Blake seems to have his sights set on her. But Elena soon discovers that Blake and his father are from another world—a world of magic, dragons, and ancient secrets. Her true identity is about to be revealed: Elena is connected to the Rubicon, the Alpha of all beasts. On her sixteenth birthday, she must claim him, or risk unleashing chaos that could destroy both the human world and the magical realm. Elena never asked for any of this. All she ever wanted was a normal life.
