Daughter of Ferdinand and Isabella, the famous catholic kings, Catherine of Aragon was a young Spanish princess known as Catalina when she left her home in the summer of 1501 to sail to England. Catherine had known since childhood that she was betrothed to Prince Arthur, heir to the throne of England, and that one day she would have to leave Spain to marry him. Now that she is fifteen, that day has come. Arriving in England, Catherine has hope for her future. Arthur appears kind, and it seems they will at least be friends. But due to Arthur's poor health, their marriage is in name only. And just six months after the wedding, Arthur suddenly dies. Now Catherine finds her once-certain future in question. As a woman she is utterly powerless to make decisions about her own life, and can only wait while those in power determine her fate. Will she be returned to Spain so that her parents can negotiate a new marriage for her elsewhere -- or will she be married to Arthur's younger brother Prince Henry, the new heir to the throne of England?
