From bestselling author and royal commentator Ingrid Seward, an inside look at the lives and loves of Diana and Catherine, the Princesses of Wales

A title in use for over 700 years, the Princess of Wales is one of the most senior positions in the British royal family. In a new book, bestselling author and royal commentator Ingrid Seward dives into two of the most recognisable and iconic holders of the title: Catherine and Diana.

Whilst they never got the chance to meet, both married into a family known the world over as The Firm. Through comparing and exploring their lives and loves, Ingrid tells the inside story of their relationship to the crown, what defines and defined their role as Princess, and just what kind of personality from outside the family ends up on the inside.
