Jonah Stone doesn't feel like anything special-his younger sister Eliza outshines him in academics, his younger brother Jeremiah embarrasses him at every corner in school, and he can't even make it through Day 1 in basketball tryouts. But that's all about to change when he discovers that his mother is a Nephilim and that as a quarter-angel, he has special powers. When his mom is kidnapped by fallen angels, Jonah and his sister must use their powers to save her. Along the way, they discover that there is a very real and dangerous war going on between good and evil and that God has a part for them to play in the war.
