Reese Witherspoon is a longtime advocate of reading, and now, she's creating her first children's book!

On Wednesday, the actress announced that her picture book "Busy Betty," inspired by her own adventures as a kid, will be published by Flamingo Books on Oct. 4.

"I've been thinking about creating a children's book with realistic young female characters since I had my daughter," Witherspoon, 45, said. "When I was a kid, I had a busy brain with a million ideas and more energy than most adults could manage, so Betty is really based on adventures from my childhood."

"Busy Betty," illustrated by Xindi Yan, follows a little girl who realizes her smelly dog Frank needs a bath before her friend Mae arrives.

"Giving Frank a bath is harder than she thought," reads the book description, "and just when everything seems impossible, with Mae's help, Betty learns she can accomplish anything with perseverance, teamwork, and one great idea."

Witherspoon has made a name for herself as an Academy Award-winning actress, producer, and author.

In 2018, the "Legally Blonde" actress released her first book, "Whiskey in a Teacup: What Growing Up in the South Taught Me About Life, Love, and Baking Biscuits." She's also the founder of Hello Sunshine, a media company that celebrates women's stories across multiple platforms. Witherspoon also formed "Reese's Book Club" and "Reese's YA Book Club" through her content company, which she sold to Blackstone.

"I'm thrilled to share Busy Betty with the world," said Witherspoon in her exclusive statement to PEOPLE, "and hope it inspires kids, especially little girls, to be creative, curious, and explore their entrepreneurial spirit."

The first in a multi-book deal, "Busy Betty" will hit bookstores on Oct. 4!
