What if there was a 13th zodiac sign?
You're no longer Sagittarius but Ophiuchus, the healer, the 13th sign.
Your personality has changed. So has your mom's and your best friend's.
What about the rest of the world?
What if "you" were the one who accidentally unlocked the 13th sign, causing this world-altering change, and infuriating the other 12 signs?
Jalen did it, and now she must use every ounce of her strength and cunning to send the signs back where they belong. Lives, including her own, depend upon it, in Kristin O' Donnell Tubb's "The 13th Sign."

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?
