The Impossible series by Nancy Werlin consists of three books published between 2008 and 2013. Impossible, the first book, introduces the concept: a teenage girl discovers that her family has been cursed for generations, with each woman in the line going mad at eighteen unless she can complete three seemingly impossible tasks drawn from the folk song “Scarborough Fair.”

Extraordinary and Unthinkable continue with different characters connected to the same curse, each facing their own set of challenges. The series blends modern teen life with fairy tale stakes, creating a reading experience that is grounded in recognizable high school settings while dealing with ancient, magical threats. Werlin’s background in realistic suspense fiction gives the fantasy elements weight, as the characters react to the impossible situations with believable fear and determination.
