The Orphans by Matthew Sullivan

It was an accident.

That was what the authorities said killed Charlie Kim's parents. And in Charlie's mind, that was how it had to be. An accident meant closure. An accident meant that the driven fifteen-year-old could move on, reassemble his life, and return to the carefully planned future that he had laid out for himself.

But then Charlie's memories of his parents suddenly begin to vanish. And suspicions arise, calling the accidental nature of their deaths into question. Charlie can't help but doubt himself and the motives of those around him...

Doubt leads to discovery. Charlie uncovers secrets that forever change his life. And thrust him and the group of teens that he is forced to unite—fellow orphans, whose parents have met similar fates—into the center of a secret battle between good and evil...

A battle dating back to the war in Heaven. A war that only Charlie and the Orphans can end. But if they hope to stand a chance against the ultimate evil, they must first overcome their own inner demons.
