Barrymore, who recently turned 40, is exprected to pen down her challenging times of growing up in the public eye, reported People magazine.
But the book is not meant to be a heavy memoir. Rather, she wants it to be bright and funny.
"I love stories that are humorous, emotional and welcoming, and that is my goal in writing this book," Barrymore said in a statement.
The book, which is not yet titled, will include stories about Barrymore "living on her own at 14, getting stuck in a gas station overhang on a cross-country road trip, saying goodbye to her father in a way only he could have understood, and many more adventures and lessons that have led to the most important thing in her life, which is motherhood," Dutton said.
The actress has two daughters with husband Will Kopelman.
