The new big wave in kids books? Advertising. Not, like, ads in the books. But kids books that are ads. Clothing giant Ralph Lauren has released an e-book for the iPad about the exploits of eight young children called the RL Gang, and narrated by the dulcet pipes of crooner Harry Connick, Jr. Reading or listening to the story, children (with their parents' credit cards, presumably) will be able to touch the characters and click through to a page where they can buy the clothes the characters are wearing.
