As winter closes in on Kirsten Swenson's hometown of Sedona, Arizona, and the world moves toward the solstice, strange forces begin to converge on the quiet desert city, seeking to bring about the destruction of everything she knows and loves.

Desperate to save her friends and family, Kirsten accepts the assistance of Martin Jones, a mysterious Man in Black who turns out to be far more than he seems. He helps to awaken the powers that have lain dormant within her...and also compels her to expose the shocking secrets buried in her past. But Kirsten soon learns that giving her heart might not be enough, and that the confrontation with the alien forces may demand her to make the ultimate sacrifice. (Book 3 of the Sedona Files)
