Harper Collins announces new imprint—Harper Muse & Once Upon a Wardrobe will be their debut novel

Updated: Jan 25, 2022

HarperCollins Focus launches new Fiction imprint Harper Muse First novel set to release October 2021

NASHVILLE, Tenn., Feb. 23, 2021 /PRNewswire/ -- HarperCollins Focus announced today the launch of its new book imprint, Harper Muse. Expanding the publishing company's footprint into general market adult fiction, Harper Muse will be under the direction of vice president and publisher, Amanda Bostic. Based in HarperCollins Focus' Nashville location, the imprint will focus on women's fiction, historical fiction and southern fiction categories with stories that resonate with Millennial and Generation X readers.

"Stories have a profound ability to connect people—especially in the fragmented world we find ourselves in today, and I could not be more thrilled to be launching HarperCollins Focus' first fiction imprint, Harper Muse," said Bostic. "We want Harper Muse to be a place where readers can escape with novels that offer hope and encouragement throughout the day—the kind of stories that continue to run through your mind days after you have put the book down."

The imprint's debut novel is set to release in the fall of 2021 by New York Times bestselling author and beloved novelist, Patti Callahan. Once Upon a Wardrobe, a historical novel set in 1950 will be Callahan's sixteenth published novel.

"The power of story to impact and change us, to connect us to each other and to open our hearts, is not only the inspiration for the new HarperCollins imprint Harper Muse but also for my new novel Once Upon a Wardrobe," said Callahan. "I am endlessly fascinated by the stories that captivate our collective imagination, and I'm delighted that my newest novel, a story inspired by Narnia's ability to captivate and enchant us the world over, will be the debut for this visionary new imprint."

In addition to Callahan, Harper Muse has signed other well-known authors like New York Times bestselling authors Ariel Lawhon (I Was Anastasia, Doubleday Books) and Kristina McMorris (Sold on a Monday, Sourcebooks Landmark), and Susan Meissner (The Last Year of the War, Berkley).

The imprint is set to release three titles in 2021 and seven in 2022. Harper Muse is part of HarperCollins Focus' key objectives to connect with great writers and readers who rely on the global reach and distribution network of HarperCollins Worldwide.

More about Once Upon a Wardrobe

Harper Muse is the first adult fiction imprint under HarperCollins Focus. With an emphasis on general market historical, Southern, and women’s fiction, Harper Muse is where readers can escape with novels that offer hope and encouragement.

The imprint’s first novels are set to debut Fall 2021, starting with "Once Upon a Wardrobe," from New York Times bestselling author Patti Callahan in October. Six additional titles will follow within the first year.

Once Upon A Wardrobe

Coming October 19, 2021

From the New York Times bestselling author of Becoming Mrs. Lewis comes another tenderly imagined and enchanting story that pulls back the curtain on the early life of C. S. Lewis.

Megs Devonshire is brilliant with numbers and equations, on a scholarship at Oxford with dreams of solving the greatest mysteries of physics.

But equations haven’t been able to solve her biggest problem: her brother George, whom she adores, has a failing heart. It has been failing for all eight years of his life. When George is given a copy of The Lion, the Witch and the Wardrobe and begs her to find out where Narnia came from, there’s no way she can refuse.

And so Megs moves completely out of her comfort zone, imploring the author and famous tutor of English Literature to give her the answers her brother so desires. What she receives instead is more stories . . . stories of Jack Lewis’s life, which she takes home to George.

Meg keeps trying to impose her trusty logic on the stories, but she slowly comes to realize that lists never answer the biggest questions. The gift she thought she was giving George turns out to be the one he was giving her: hope.
