Grayson Phillips, a normal 18 year old young man, is about to find out he is not as normal as he thought he was. On top of the odd fact that he has to contend with a lifetime friend named Jo, a woman who no one else can see but Grayson, and a best friend, Harry, who is in love with him, he will discover that he is very important to the safety of Earth, and danger is looming.
