What is the main conflict in Shakespeare's Champion by Charlaine Harris?

Shakespeare's Champion by Charlaine Harris revolves around the character Lily Bard, and the small Arkansas town of Shakespeare. Lily Bard moved to Shakespeare four years ago, searching for peace after a brutal rape and mutilation that had obviously changed her life forever. Though Lily does not focus on her past, it is obvious it affects her every day, from the relationships she forms to the constant trips to the gym to strengthen her body. Body Time is where Lily works out and take karate class, and is owned by her sometimes lover, Marshall Sedaka. Marshall's illness requires Lily to open the gym one morning, which is how Lily comes to find the body of Del Packard, his neck crushed under the weight of a barbell.
