Madeline's Miracles — Warren Adler

An artist, her stockbroker husband and their twin daughters move to Los Angeles and unwittingly fall prey to a Madeline, a self-professed "psychic" and can foresee their future. By persuading them that she holds the key to their success and can protect them from danger, Madeline gradually takes full control over their lives, their careers, their parenting - even their sex lives, until they become her willing accomplices.
This page-turning thriller rises to a tense crescendo as Madeline manipulates the family's beliefs and paralyzes their will to protect themselves. A chilling and in depth look into the how power of suggestion can wreak havoc on the unsuspecting and gullible.
