The Emerald Talisman (Talisman, #1)

To be normal, sixteen-year-old Julia Parker would shed her empathic gift in a second. Life has been difficult since her mother's mysterious disappearance ten years earlier - an event she witnessed, but can't remember. Julia's situation becomes more complicated after a near death experience from a blood thirsty stalker. As high school students go missing it is clear there is a connection to her own experience--past and present. Someone has to stop the madness and a chance encounter with a creepy psychic foretells that only Julia is the key to stopping the madness, but it may require the life of the one she loves.
