Sixteen-year-old Jane Grey--the "Nine-Day Queen"--is a quiet and obedient young lady destined to become the shortest reigning English monarch. Her beautiful middle sister, Lady Katherine Grey charms all the right people, until a scandalous love affair causes loyalties to shift. And finally, Lady Mary Grey is a dwarf with a twisted spine whose goal is simply to protect the people she loves--but at a terrible cost.
 
In an age in which begetting sons was all that mattered and queens rose and fell on the sex of their child, these three girls with royal Tudor blood lived under the dangerous whims of parents with a passion for gambling. The stakes they would wager: their daughters' lives against rampant ambition.
