She is fast becoming the envy of her hip, 30-something girlfriends when Geoff dumps her for Bree, his massage therapist. With nothing to show for her short marriage but a couple of minor brushes with the law and a tiny drinking problem, Amanda escapes to Hollywood Beach, 20 miles south of Santa Barbara, to focus on her career as professional organizer and “Messy Girl” blogger for a small local newspaper.When Bree is found murdered on the beach behind Amanda's house, her life spirals into chaos. Detectives single her out as a person of interest. With few people listening to her side of the story, Amanda resorts to her own devices to clear her name.
