It’s tough being a best-selling author. Just ask Janet Evanovich, who has discovered that signing books can be a real pain. Evanovich, who wrapped up a six-city book tour Monday, is sporting a brace on her right hand. Fearless Fourteen, her new novel starring New Jersey bounty hunter Stephanie Plum, enters USA TODAY’s Best-Selling Books list at No. 1. The tour started June 17 at the MGM Grand Theater at the Foxwoods Resort & Casino in Mashantucket, Conn., and drew more than 2,000 fans. Huge crowds also showed up in Omaha, Denver, Dallas, San Diego and Los Angeles. "It’s at least 1,000 people at each signing, which goes on for at least five hours, and they all have four or five books," Evanovich says. "The human thumb is not designed to do that six days in a row."
