Faced with abominable working conditions, unsympathetic owners, and hard-hearted managers, the mill girls of Lowell have had enough. They’re going on strike, and they have a secret weapon on their side: a little witchcraft to ensure that no one leaves the picket line.

For the young women of Lowell, Massachusetts, freedom means fair wages for fair work, decent room and board, and a chance to escape the cotton mills before lint stops up their lungs. When the Boston owners decide to raise the workers’ rent, the girls go on strike. Their ringleader is Judith Whittier, a newcomer to Lowell but not to class warfare. Judith has already seen one strike fold and she doesn’t intend to see it again. Fortunately Hannah, her best friend in the boardinghouse-and maybe first love?-has a gift for the dying art of witchcraft.
