Dylan Peterson and the Angels of Fire (Dylan Peterson, #1)

Dylan Peterson, 17, was an average kid living an ordinary life. He worked hard to get good grades in school, he had a crush on a girl, Naomi, who is out of his league, and he was in constant competition with his younger brothers; until one fateful afternoon when his normal life abruptly became extraordinary.
He was selected by the Great Protector to become a member of the Guardian Angels who are sworn to protect all life on Earth. Their greatest threat is an unimaginable evil seeking to cast the world into eternal darkness. The Angels fight to banish the darkness but it ruthlessly preserves.
Dylan must learn to harness and wield a blue flame in order to protect his home and those he loves. Training with Naomi and other Angels, it quickly became apparent that he and Naomi share a power no other Angel possesses. Could they be the key to finally stopping the darkness once and for all?
