Child of Tempus (Book One in the Gods' Scion series)

Rodrick is a prince of the ruling country of Diar. He has a face kissed by the Gods themselves, with deep blue eyes and long ruby-red hair. Speaking of Gods, he also happens to be the Acolyte of Time. Gifts and curses with this power give him control over aspects of time. And being a dragon-human hybrid has its amazing perks too. But since childhood, Rodrick has had a target on his back, and his insanely power-hungry father, Demon King Ryton, comes across as his closest but worst enemy. Throw in the workings of an alcoholic mother, a bipolar sister, a recovering addict brother, and an adopted little sister with magical powers, and you have the royal family of Diar. Things couldn't get any worse, until he meets the beautiful Princess Arcelia—but Arcelia isn't the main problem. Her and Rodrick are on now on the run from Rodrick's father, Ryton. And with the looming risk of world destruction ahead of them, Rodrick is worried about more than college exams.
