American tennis star Serena Williams is writing a book, The Adventures of Qai Qai, about daughter, Olympia’s favourite doll. The book will be released next

The doll Qai Qai became an internet sensation in 2018 when Williams gave the doll its own Instagram account. Entertainment technology firm, Invisible Universe, which made Qai Qai’s social media page funny, will be assisting the former World No. 1 tennis ace with the book.
