The Adventures of Qai Qai, a new book by
Serena Williams, has made its way to the top of Amazon's list of new best-sellers.
Williams' husband Alexis Ohanian has thanked readers for helping to get the children's picture book off to a great start.
"THANK YOU for making @RealQaiQai, number one on Amazon today. WTG @serenawilliams," Ohanian tweeted.
The illustrations for the book that Williams authored have been done by Yesenia Moises.
The idea for the book, which went on sale on September 27, was based on a doll that belonged to Williams' daughter Olympia.
The 41-year-old had earlier revealed that the book had some great messages for children which revolved around self-confidence and believing in oneself.
"It's so authentic. It's a story that we came up with during COVID and this particular book of Qai Qai is just about using our imagination because kids have such an amazing imagination," Williams said on ABC's Good Morning America show while promoting the book.
"We couldn't leave the house and I was playing with Olympia and our doll Qai Qai who is this amazing personality on social media platforms and yet we just like wanted to put in people's minds that we can't forget just how important it is to use your imagination and play and also believe in yourself."
