Sold out on day one. Author Shobhaa De's new book on marriage, Spouse, has sold 10,000 copies within a day of it hitting the market Tuesday.

"Spouse has created publishing history in India," De tells. "(It has gone) into a reprint on day one.

"I'm proud of that and glad that my 14th title is a best-seller too, like the earlier ones."

Born in Maharashtra in 1948, De has been one of India's top columnists and authors. With a degree in psychology, De founded and edited three popular magazines - Stardust, Society and Celebrity.

Her best-selling novels include Socialite Evenings, Sultry Days, Starry Nights, Sisters, Speedpost and Surviving Men.
