On Tuesday, the book ‘Amalia’ will be released in The Netherlands. The book was written by Claudia de Breij to mark Princess Catharina-Amalia’s upcoming 18th birthday on December 7th and is based on personal encounters with the heir to the throne this past summer.

This book follows the tradition of books being written for the Dutch heirs’ 18th birthday as was the case for King Willem-Alexander in 1985 and Princess Beatrix in 1955. Ahead of the book release tomorrow, the Dutch court shared a few private photos of Princess Catharina-Amalia that are shown in the book.
