The #1 New York Times bestseller returns with a completely new setting-the magnificent natural beauty of Sun Valley, Idaho-and a heart-stopping story in which a local sheriff struggles to protect a controversial politician from the elegant plan of a hired assassin.

Eight years ago, in Sun Valley-snowcapped playground for the wealthy and ambitious-all that stood between U.S. Attorney General Elizabeth Shaler and a knife-wielding killer was local patrolman Walt Fleming. Now Liz Shaler returns to Sun Valley as the keynote speaker of billionaire Patrick Cutter's world-famous media and communications conference, a convergence of the richest, most powerful business tycoons. The controversial attorney general is expected to announce her candidacy for president. It's a media coup for Cutter-but a security nightmare for Walt Fleming, now the county sheriff.

As the Cutter conference gets under way, authorities learn of a confirmed threat on Shaler's life, and various competing interests-the Secret Service, the FBI, Cutter's own security forces -begin jockeying for jurisdiction. Amid the conference's opulent extravagances, Walt is suddenly shaken by an apparent murder, his nephew's arrest, and a haunting legacy from his family's past. The clock ticks down toward Shaler's keynote address as we track the chilling precision of her assassin's preparations.
