Thoroughbred

Hi everyone!
Any horse fans here? Anyone like horses at all? If you do, then you would REALLY like this series!
Thoroughbred is a series about horses. You hear from the main character's point of view and hear their adventures with their horses. They race with them, save them from colic and other dangerous horse diseases, and much more.
The main character switches as they grow up. For the first few books, you hear from Asheigh's point of view. When she grows up, you hear from Samantha's point of view. When she grows up, you hear from Cindy's point of view. I'm on book twenty-nine, (there's more than seventy books!), and I'm listening to Melanie's point of view.
Anyway, this series is REALLY, REALLY, REALLY, good!
