From USA Today. Book Buzz: 'Water for Elephants' goes Hollywood

Rob Pattinson and Reese Witherspoon grace the jacket for the movie tie-in; "Super Diaper Baby 2" is here; and books play a numbers game.

'Water' world: On Tuesday, two pretty faces —Robert Pattinson's and Reese Witherspoon's — will begin gracing the jacket of Water for Elephants as the movie tie-in paperback edition hits stores. The film isn't in theaters until April 22, but advance publicity has helped boost sales of the 2006 novel about a traveling circus. This week it's No. 8 on USA TODAY's Best-Selling Books list. The highest the novel has been is No. 4, in August 2007, after it was first released in paperback. Publisher Algonquin says the star-studded new jacket will have an impact: "I expect we'll see a huge increase in sales of all available editions, including e-books and audio," says associate publisher Ina Stern. Meanwhile, the paperback of Gruen's 2010 novel Ape House will be released April 5.
