Spanning over five decades, The Sisters is the story of two sisters, Mabel and Bertie. Once very close, a series of unfortunate circumstances tears them apart, and the rest of the book follows their lives and how they handle being apart from each other. I thought this novel was done very well without becoming too melodramatic. Much of this novel is very dark, especially the beginning when the mother dies and the step-father becomes abusive, but other than that it just follows how two sisters overcome adversity and go on to have fulfilling lives. I highly recommend it to all readers who like thought-provoking stories.
