Selling Hope — Kristin O'Donnell Tubb

It's May 1910, and Halley's Comet is due to pass thru the Earth's atmosphere. And thirteen-year-old Hope McDaniels and her father are due to pass through their hometown of Chicago with their ragtag vaudeville troupe. Hope wants out of vaudeville, and longs for a "normal" life -- or as normal as life can be without her mother, who died five years before. Hope sees an opportunity: She invents "anti-comet" pills to sell to the working-class customers desperate for protection. Soon, she's joined by a fellow troupe member, young Buster Keaton, and the two of them start to make good money. And just when Hope thinks she has all the answers, she has to decide: What is family? Where is home?
