What is the main Idea of the book Don't Look Behind You

Family is an important theme in Don’t Look Behind You. At the beginning of the story, April has a picture perfect family; her mother is a famous author, her father works for an airline company, and she plays competitive tennis. They live in a nice house, and are comfortably wealthy.

When the family is forced to go into hiding, cracks begin to appear between them. Even when the family is confined to a hotel suite, they spend their time separately, with April watching soap operas, Bram watching game shows, and Mrs. Corrigan writing and then beginning to drink to cope. April puts her boyfriend above her family’s safety and sends him a letter that results in the family being located by Mike Vamp.
