She embarked on a new, thematically connected series of historical fiction excavating the stories of important, complex and fascinating women from the past with THE OTHER EINSTEIN, which tells the tale of Albert Einstein's first wife, a physicist herself.

She then released CARNEGIE'S MAID, the story of a brilliant woman who may have spurred Andrew Carnegie toward philanthropy, followed by the B&N Book Club pick and NYTimes bestseller THE ONLY WOMAN IN THE ROOM, the tale of the Golden Age of Hollywood actress Hedy Lamarr who made a world-changing invention, and LADY CLEMENTINE about Winston Churchill's wife.

She then wrote the Costco pick and NYTimes bestseller THE MYSTERY OF MRS. CHRISTIE which focuses on the real-life disappearance of Agatha Christie and the role it played in shaping her into the world's most successful novelist.

In her first co-written novel with the talented Victoria Christopher Murray, Marie released the NYTimes bestselling and Good Morning America Book Club pick THE PERSONAL LIBRARIAN about Belle da Costa Greene, the personal librarian to J.P, Morgan who hid a secret about her identity -- and that was followed by HER HIDDEN GENIUS about the brilliant British scientist Rosalind Franklin who discovered the structure of DNA but her research was taken and used by James Watson and Francis Crick.

Coming this January 2023 is THE MITFORD AFFAIR, an explosive novel of history's most notorious sisters -- the brilliant, aristocratic Mitfords --, one of whom will have to choose her country or her family as the sisters get caught in the crosshairs of WWII."
