St. John delivers on the promise of her 2020 debut, The Lion's Den, with this superb tale of revenge and unbridled ego. Actor Cole Power, who at 49 is still considered by many to be one of the sexiest men in Hollywood, is financing a film titled The Siren that was written by his son, a recent film school graduate, who will also direct. Cole's ex-wife, Stella Rivers, who's counting on the movie to revive her flagging career, will star opposite Cole. Taylor Wasserman, the producer, is also desperate for a hit after being fired from her previous job amid rumors of embezzlement. Also involved are Felicity Fox, Stella's beautiful new assistant who seems too good to be true, and social media influencer Madison Kasabian, whose vanity knows no bounds. The troupe assembles on the Caribbean island of Saint Genesius, and the scene is set for action, intrigue, murder, and heart-stopping adventure. St. John keeps readers deliciously off-balance with each new revelation about the characters and their motives, as revealed through the alternating viewpoints of Stella, Felicity, and Taylor. This is pure, riveting entertainment. Agent: Sarah Bedingfield, Levine Greenberg Rostan Literary. (May)
