Times are tough for sixteen-year-old Stick McLaughlin, running from a trumped up arson charge and hiding among hobos in 1918 Boston. Denied the companionship and support of lifelong soul mate Ellie, Stick edges her way through prison as "Mac," only to be thrust alone and wide-eyed into the very definitely Roaring Twenties. She swallows what's left of her pride through the final year of her sentence-serving as maid to a wealthy family-but stockpiles many invaluable lessons about rapidly-changing life in 1924. Confrontations with bootleggers and a particularly enthralling flapper go a long way toward molding a strong, confident, clever "Mac," who hits the streets with a gang of her own, determined to claim the good life she deserves by beating the corrupt system and Boston's ethnic mobs at their own game. Little does she know that the lost love she's mourned for years is closer than she thinks. But have time and circumstance conspired against her once and for all?
