The Rowan — Anne McCaffrey

Even as a child, the Rowan was one of the strongest Talents ever born. Telepaths across the world had heard her mental distress calls when her family's home was suddenly destroyed....Years later, she became a Prime Talent, blessed with a special power which stretched across the stars. But without family, friends--or love--the Rowan's power was not enough to bring her happiness....

Then a telepathic message came from a distant world facing an alien threat, a message sent by an unknown Talent named Jeff Raven.

Now--be it power, danger, or love--the Rowan is about to meet her match.
