Twisted

Read Twisted Storyline:

Who will be next?
Though former FBI Special Agent Sloane Burbank once survived a life-threatening injury in the line of duty, she now uses her specialized skills as an independent consultant. But when one of her closest childhood friends mysteriously disappears, Sloane takes the case—even though her ex-lover Derek Parker is the FBI agent in charge.
Special Agent Derek Parker has no time to spare for a dead-end case—especially since it would mean working with a woman he never expected to see again. But as more women disappear and others turn up brutally murdered, he and Sloane come to the sickening realization that these random crimes are linked to the same crazed killer, a fiend with a mind so psychotic, so twisted, that it will take everything Sloane has to capture him—even as she becomes his latest target.
