The Second Chance Horse

Catherine Bronwyn is a successful horse rider in the world of equestrians. She started riding when she was eight and first competed in hacking and riding show horses, however since then she has started eventing. She is number 1 in Queensland, Australia for dressage for her age group 3 years running, has won at nationals for hacking twice and has placed second at nationals for the 2015 young rider three day event.
Catherine, or Cat as she is know as to her friends and family, has owned four different horses up until the age of 15 which she is now. She has kept all of her horses on her family's 25 acre property, and is now on the lookout for a new young eventing mount to take her to the next level.
What happens when instead of buying a young horse with impeccable eventing bloodlines she buys a second chance horse that has been badly abused and almost sold to the doggers yard? Will her new horse Chance become her next successful horse or will he fall back to be a skinny, scared gelding once again?
