Time Warner Book Group lands two books in the top spots on our hardcover charts. In fiction, it's James Patterson's

London Bridges, with a 1,130,000-copy first printing. It's the 10th Alex Cross thriller (the first, Along Came a Spider, was published in 1993). Little, Brown notes that the series has sold about 29 million copies, with more than $330 million in gross revenues; all 10 books have been translated into 31 languages. Patterson is visiting 11 cities on his "Naughty and Nice" tour; he's also promoting his first children's book,

santaKid. Little, Brown reports 500,000 copies in print; it's #8 on the NYT children's list for picture books on November 28. This year's holiday window display at Saks Fifth Avenue in Manhattan features a re-creation of santaKid.

Landing in the #1 spot on the nonfiction list is

The Perricone Promise: Look Younger, Live Longer in Three Easy Steps by Dr. Nicholas Perricone. Warner Books had planned a 177,000-copy first printing but has already gone back to press seven times, for a total of 627,000 copies. Perricone's earlier titles on reversing the aging process were all national bestsellers. Back in 2000, The Wrinkle Cure was published by Rodale Reach and had a four-week run on PW's hardcover charts. The Warner trade paperback was on our list for 27 weeks and has 962,000 copies in print. Two years later,

The Perricone Prescription, published by Harper Resource, had an 11-week run on our charts and currently boasts 600,000 copies in print. The trade paperback also lands on this week's list, in the #7 spot with 200,000 copies in print. The doctor has already done a TV satellite tour, a radio satellite tour and, on November 11, he was one of the featured guests on an Oprah program called "Take 10 Years Off in 10 Days." Watch for more sales beginning November 26, when PBS will begin airing its pledge drive featuring Perricone and his new books; it runs until December 12.
