On Thursday—Percy Jackson’s birthday—Disney Worldwide Publishing announced that The Son of Neptune, the second installment in Rick Riordan’s The Heroes of Olympus series, will have a three-million-copy first printing, the largest in the company’s history. Leading up to the novel’s one-day laydown on October 4, the publisher is staging an Olympian Week that will include outdoor celebrations in New York City and Los Angeles, seven bookstore events that Riordan will attend, and a presentation of pictures and video clips of the outdoor festivities on the series’ Web site.
