In this month's competition, we are giving you the chance to Win a copy of Spare: by Prince Harry in Hardcover.

It was one of the most searing images of the twentieth century: two young boys, two princes, walking behind their mother's coffin as the world watched in sorrow-and horror. As Princess Diana was laid to rest, billions wondered what Prince William and Prince Harry must be thinking and feeling-and how their lives would play out from that point on.

For Harry, this is that story at last.
