The mustang challenge

Serena Spearhart was what seemed to be a genius with horses. After breaking a colt who seemed hopeless she was selected to be in the mustang challenge. 3 girls and 3 boys will compete against 45 other contestants. She will have to break one of the untouched creatures to be safe to ride and compete. But when Serena is given a extremely difficult horse hope is nearly lost. But will she finally figure the horse out while digging into her mothers past?
