30 Days In May — Wayne Hancock

The year is 1904. The place is St. Louis. The World's Fair has just arrived. And so have two girls from the country. What they see and experience is way beyond their expectations-with wonderful sights and shocking murder!
Readers are in for a treat as they follow the summer adventures of Katie and Pearl, small town-town girls who learn first hand about the lives of the rich and powerful. But they also are swept up in the heinous acts of mobsters who will stop at nothing to take what they want.
