Sixteen-year-old Eva De Puebla comes to England in 1581 as lady in waiting to Catherine of Aragon, the Spanish princess who is to marry Prince Arthur, heir to the throne of England. Eva has been chosen to accompany Catherine because she is her close childhood friend. But as the years go by, although the girls remain friends, their lives grow far apart. Arthur dies not long after the marriage, and though Catherine is eventually able to marry the younger brother and new heir, Henry, their marriage becomes strained as Catherine fails to produce a living child. Meanwhile, Eva has found happiness in love and marriage and having a child, but mourns for her dear friend's lost dreams.

This book is written in the form of Eva's diary from 1501-1513.
