Leanda de Lisle, The Sisters Who Would be Queen.  Harper Press, London, 2008.  ISBN 978-0-00-728043-8

This is the interesting story of the three Grey sisters,  two of whom are little known.  “Nine Days Queen” Jane is more of a rebellious leader than the innocent victim of power seekers that history has painted her.  And after her execution, survival was the name of the game for her sisters Katherine and Mary.
