As if tracking down train robbers wasn't hard enough, now Sheriff Jericho Silver's backup has arrived, and she's a gun-toting, head-turning beauty. She sure spells trouble. Madison O'Donnell had the perfect life, a beautiful home and all the ladies' luncheons she could stomach, but it left her bored to tears. Now a widow, she's determined to fill her days with daring deeds and wild adventures. Jericho is equally determined that she'll be on the next train home. But this is one lady who won't take no for an answer.
