内容简介：
The "Greys" are an alien race, long blamed for abductions and experiments, and now they've found their next specimen. Hunter Stone is a typical teenager who has no idea he has been chosen to be part of an elite group of warriors, the Da'Sheal. Together, they will fight an intergalactic war to save the "Greys" from obliteration. Now Hunter is back on Earth with special abilities and no recollection of how he got them. As he adjusts to the future and his new life, he uncovers the secret past of his family and discovers that his abduction may not have been a random event.
