Aaron meets Vilma Santiago, a beautiful girl at his high school to whom he is immediately attracted. It seems like things are finally working out for Aaron; he has everything that he has ever wanted, so he thinks. On his 18th birthday, everything changes. He starts having nightmarish dreams and visions, has trouble concentrating, experiences bad headaches, starts hearing voices in his head and feels painful changes occurring inside his body. Other weird things start happening, too. Suddenly, he has the "gift of tongues" and can speak and understand languages he had never known; he can even understand his dog Gabriel talking to him. Surely Aaron is losing his mind. He reacts to this transformation with confusion; just when his world seemed normal, it now begins to unravel before his eyes.
