Of Spellbooks and Thieves - The Legends of Anticuus, #1

Magic is a powerful yet fleeting thing. Those blessed with its presence are given a choice: to do good for their fellow man or to be corrupted. Tobias has neither magic nor the pressure of its power and has lived a peaceful, secluded life because of this. That is, before he stumbles across the key to power: a spellbook. Desperate to unlock its secrets, he accepts it as the promise of something greater. Until the day a thief snatches the book out from under him.
In an effort to get it back, Tobias is thrust out into the dangerous world beyond the comfort of his home. Dragons, secrets, and wild magic lurk around every corner he turns, and he has no hope of catching the thief on his own. In order to reclaim his book and safely return home, Tobias must learn to adapt to the shifting world outside. But as he is joined by others who volunteer to aid him in his search for the thief, he realizes there's more to her than he thinks, and the spellbook is only the beginning.
