While sales of Mr. King's first book of 2002, "Everything's Eventual," a story collection, nearly matched those of his 2001 novel, "Dreamcatcher," his second book, the novel "From a Buick 8," fell short. "From a Buick 8" has sold 367,000 copies, about a 20 percent decline, according to Nielsen Bookscan, which gathers sales data from outlets that represent about 70 percent of total sales.
