Meghan Markle released a sweet message to supporters on Wednesday, just after her new book, The Bench, reached the #1 spot on The New York Times bestseller list for childrens picture books this week.

While this poem began as a love letter to my husband and son, Im encouraged to see that its universal themes of love, representation and inclusivity are resonating with communities everywhere, she said in a release shared on Meghan and Prince Harrys Archewell foundation website.

In many ways, pursuing a more compassionate and equitable world begins with these core values, she added. Equally, to depict another side of masculinity one grounded in connection, emotion, and softness is to model a world that so many would like to see for their sons and daughters alike. Thank you for supporting me in this special project.

The book was inspired by Prince Harrys relationship with the couples son, 2-year-old Archie Harrison Mountbatten-Windsor, and looks at the special bond between father and son as seen through a mothers eyes.

The Duchess of Sussex collaborated on the book , which was released on June 8, with the award-winning illustrator Christian Robinson. She spoke warmly of Robinsons watercolors in a statement announcing the books publication last month.
