The guilty one

"The day Ron Isherwood calls Maris Vacanti from the Golden Gate Bridge, asking if he should jump, is the day Maris's world completely transforms. Maris has been consumed with grief and anger since her teenage daughter was found dead at the hands of Ron's son. Her marriage is in pieces and her routine shattered. Now, burdened with a terrible choice by a man whose existence is forever entwined with hers- a fellow parent breaking under the weight of the past- she gathers her courage and walks out on her sheltered suburban life."
