"Cat sets out to discover what happened to her childhood friend when she discovers that he's been missing for months"--
Mary Catherine Montgomery hasn't been to Montgomery Falls since she was twelve years old-- and discovered she could do things that no normal twelve-year-old could do. Since she had her first kiss with Riley Fraser. Five years later she's back, and finds that Riley disappeared three months ago. When Noah, Riley's brother, asks for help in discovering what happened, Cat is torn between wanting to learn the truth and protecting the secret that she has been guarding ever since that summer she and Riley stopped speaking. When a girl is discovered floating in the river, barely alive with no knowledge of who attacked her or why, Cat must make a choice. She can use her ability to discover the truth and find Riley-- or keep running away from a power she can't control. -- adapted from jacket and perusal of book.
