Soda Pop is a story about a pony and the children who owned her. The pony begins life with Mya, a young girl, on a large ranch owned by her grandparents. Mya begins training Tinkerbell, as the pony is known, within days. Her Uncle Rusty helps her with the training from the outset. When Myas grandfather dies suddenly, the family decides to shut down the ranch. Rusty sells off the stock, and by mistake, friends take Tinkerbell to the auction. Tony works for his father as a trainer at a horse trading stable. He works with Windy, as he calls the pony, and soon has her jumping. Tony falls in love with the pony, but his father sells Windy to a colonel from Fort Sam Houston. The colonels son, Clayton Jr., wants nothing to do with the pony. He never even names her. On the first day of him riding her, Clayton Jr. falls off, and Clayton Sr. orders her to be sold for dog meat. Instead of selling her, Hank, a stable hand takes her to his niece near Junction. There, Sarah calls her Jasmine and uses her to herd goats. A major flood takes Jasmine away. Soda Pop ends up in another auction and is bought by Teresa for her son Joshua. This is to be her forever home, and Mya, from the first of the story, is the vet who takes care of her.
