Zoey's family has a strange feeling about the two-tailed comet in the sky. But that doesn’t mean Zoey will let them chaperone her class field trip to Reelfoot Lake, Tennessee—especially since Grandma Cope grew up near there. What if Grandma tells everyone about being a Native American? Zoey has no interest in her family’s past. All she wants is for her parents to get back together, and for herself to fit in at school. She doesn’t know what’s hit her when, during the bus ride to Reelfoot, she’s propelled back in time to 1811, when the lake was formed! Now Zoey’s cell phone doesn’t work, there’s no fast food in sight, and massive earthquakes keep rattling the land. Prim, proper Prudence Charity and her way-too-pregnant mother are the first people Zoey sees, but they don’t believe her story—until they meet up with Chickasaw Chief Kalopin and his beautiful Choctaw bride. Kalopin is convinced that the Great Spirit has cursed him for stealing Laughing Eyes from Chief Copiah, and that soon, the river will swallow up his village and everyone in it. Zoey knows they’re headed for disaster, but can she find the courage to save them?
