Aaron's senior year has been anything but typical. Half-angel and half-human, he has been charged to reunite the Fallen with Heaven. But the leader of the Dark Powers is determined to destroy Aaron--and all hope of angelic reconciliation. Struggling to harness the incredible force within him, Aaron trains for the ultimate battle. With the Dark Powers building in strength and numbers, their clash may come sooner than he expects. And everyone who's ever mattered to Aaron is now in grave danger. Aaron must protect the girl he loves and rescue the only family he's ever known. Because if he can't save them from the Dark Powers, how can he hope to save the Fallen? 
 There's a lot more action in this one so you'll never be bored. The plot really centers on Aaron coming to terms with his destiny and how he's trying to save Stevie, who was kidnapped by the Powers while at the same time, trying to help the residents of Aerie. 
 What I liked about this series is that while it handles quite a lot of actual Christian/angel mythology, it doesn't preach Christianity at all. It doesn't deal with the bible or whether God loves non-believers as much as believers, etc. It sticks strictly to nephilim mythology and written by a male author, it doesn't have an overwhelming amount of romance, which is a good balance with the action. 
 Definitely a series I'd recommend. 3.5 stars.
