The Dollmaker's Daughters by Dilly Court

A powerful saga set in turn-of-the-twentieth-century London from the Sunday Times bestselling author. 

For Ruby and Rosetta Capretti life in the slums of the East End holds little promise. 

Although very similar in looks they dream of very different futures. Coquettish, flamboyant Rosetta is desperate to leave the claustrophobic confines of the sewing sweatshop to follow in her wayward aunt's footsteps and work under the bright lights of the music hall. Ruby, quieter and more modest, has always longed to train as a nurse, a pipe-dream for a girl from her humble background.
