The book, 'De Dybeste Rødder' or 'The Deepest Roots', marks yet another venture for the multi-talented monarch, who is an accomplished artist, translator, illustrator and costume designer.
It is also an appropriate one for the present scion of the world's oldest surviving monarchy, founded by the Viking kings Gorm the Old and Harald Bluetooth, back in the 10th century.
“It has been a privilege to be able to write this book,” the Danish journalist Thomas Larsen, who worked with her on the book, said in a press release. “She puts colour and personality to the story.”
In the book the Queen describes how Denmark has changed during her reign, moving from poverty to riches, rural to urban, at the same time as women have become equal.
She also argues that Denmark has "...gone from friendly curiosity to skepticism about immigration”.
Margrethe began her public art work as early as the 1970s when she illustrated the Danish edition of Lord of the Rings, under the pseudonym Ingahild Grathmer.
She designed the costumes for a production of the Danish ballet A Folk Tale by the Royal Danish Ballet, and she has also illustrated Cantabile, a book of poetry by her French husband Prince Henrik of Denmark.
The book will be published in Denmark on October 27.
