When the Circle C ranch decides to host a rodeo competition with two other ranches, dozens of cowboys are eager to prove they're the best riders and ropers in the valley. But they're not the only ones who want to show off their skills--Andi aims to lasso her way to the prizes, even if big brother Chad says the contest isn't for kids.

The roundup is meant to be a time for food, fun, and friendship. But before Andi can prove she's got what it takes to be a real cowgirl, the day turns dangerous. Will a friendly rodeo turn into a range war between ranchers and sheepherders? Can Andi and her family keep their neighbors--and themselves--safe?
