Sisters, Suspense, Contemporary 

After a demanding book tour, superstar mystery novelist Grace McCabe decides to visit her sister, Kathleen, who’s embroiled in a custody battle after a bitter divorce. Arriving in D.C., Grace is shocked to find Kathleen living in a run-down neighborhood and, hoping to afford a hotshot lawyer, supplementing her meager teacher’s salary by moonlighting as a phone sex operator. According to Kathleen, Fantasy, Inc., guarantees its employees ironclad anonymity. But Grace has her doubts—which are confirmed one horrifying cherry-blossom-scented night when one of Fantasy, Inc.’s operators is murdered. As Grace is drawn to help solve the crime, her life turns into a scene from one of her own books. Yet as one of her biggest fans, investigator Ed Jackson, warns her: This isn’t fiction. Real people die—and Grace could be next. For she’s setting a trap for a killer more twisted than anything she could imagine. And not even Ed may be able to protect her from a rendezvous with lust and death. - from Amzon
