Bad Apple: Book One of the Warner Grimoire

Hidden from the world of magic since birth, Simon Warner is a 14-year-old with a problem. A near-death experience has triggered his latent powers, and with them comes the threat of an evil legacy that, left unchecked, will transform him into an unspeakable monster.

Just like his parents.

For the first time in his life, Simon understands what he is, but he has never been more afraid of what he could become. When his adopted father disappears mysteriously, Simon must risk entering the world of magic to save him, but the price may just be every last bit of goodness in him. Unless he learns to control the rage growing inside of him, Simon will become an evil the likes of which the world has never seen.
