Meghan Markle's new children's book, called The Bench, has failed to reach Amazon's top 200 bestseller list following the release on June 8, standing on the 204 in the charts.
The Duchess of Sussex's work was widely criticized as "semi-literate" and uninspiring.
"We didn't enjoy this book at all - I have no idea why the author thought this story would appeal to children. It's incredibly boring and uninspiring," one of Amazon's reviewers wrote.
The book is dedicated to the relationship between Prince Harry and their first-born son Archie, 2, but also includes a nod to the couple's newly-born daughter Lilibet "Lili" Diana.
The Bench's final picture features a military-uniformed man in a garden helping a young boy feed chickens while a woman stands in the house by the window cradling a baby. The illustration is accompanied by the words: "Looking out at my love and our beautiful boy. And here in the window, I'll have tears of great joy." Markle announced earlier that the book was inspired by a poem she wrote for her husband on Father’s Day 2019.
This comes weeks after Kate Middleton's photography contest book "Hold Still" continues to soar after it went on sale.
Meghan Markle and Prince Harry's second child Lily was born in California on Friday, June 4. Both mother and child are reportedly healthy and well, and settling in at home.
