It is exactly one week until sixteen-year-old Mercy Swimmer is to play out a dream scenario: to spend an entire week with movie star Fiona Wonder, the prize awarded to the winner of a contest staged by a teen magazine.Mercy is kind and compassionate and always tries to see the best in everybody, even when those around her do not respond similarly. For example, her mother’s snippy, hot-tempered friend Nikki is a kleptomaniac who constantly belittles her boyfriend. Her best friend Valerie has anger issues and a weight problem. Beautiful but cold Lady Redding, Valerie’s mother, feels entitled to everything even as others go without. And Mercy’s mother, a severe asthmatic who works two menial jobs in a "dead mall", seems to care more about Fiona Wonder and Mercy’s upcoming week with her than the pressing issues in their own lives.Everything is on track for Mercy’s upcoming week with Fiona Wonder, but when her mother’s asthma flairs up, Mercy’s world turns upside down and she is faced with a decision that will ultimately challenge her own capacity for compassion.A Week with Fiona Wonder shines an intense light upon the dire consequences of social exclusivity and suggests the alternatives of inclusion, empathy and, indeed, mercy.
