Murder on the Iditarod Trail by Sue Henry

The winner of Alaska's world-famous Iditarod -- a grueling, eleven-hundred-mile dog sled race across a frigid Arctic wilderness---takes home a $250,000 purse. But this year, the prize is survival. Only the toughest and the most able come to compete in this annual torturous test of endurance, skill, and courage. Now, suddenly and inexplicably, the top Iditarod contestants are dying one by one in bizarre and gruesome ways. Jessie Arnold, Alaska's premier female "musher," fears she may be the next intended victim, but nothing is going to prevent her from aggressively pursuing the glory and the rewards that victory brings. Dedicated State Trooper Alex Jensen is determined to track down the murderer before more innocent blood stains the pristine Alaskan snow. But Jensen's hunt is leading him into the frozen heart of the perilous wild that Jessie Arnold knows so well -- a merciless place far from any vestige of civilization, where nature can kill as fast as a bullet...and only the Arctic night can hear your final screams.
