Pony Club Secrets is a series of junior and intermediate reader children's books published by HarperCollins in the United Kingdom.
The series was created by author and journalist Stacy Gregg, and is loosely based on her experiences as a young rider growing up in New Zealand.
Her best friends are Stella Tarrant and Kate Knight, and her enemy is Natasha Tucker (owner of Goldrush).
Tom used to be a famous eventer in his youth, but after seriously injuring himself whilst competing at Badminton horse trials, he had to retire from the sport.
However he is particularly close to Issie and is the one who brought her Anglo-Arab mare Blaze to her after rescuing her with the help of ILPH (International League for the Protection of Horses) which he works for.
In Angel and the Flying Stallions, he marries the head trainer of El Caballo Magnifico, Francoise D'arth, who returns to Chevalier Point to train the dressage there.
The bratty blonde is always making nasty remarks about Issie, and by the end of Fortune and the Golden Trophy they are full-fledged enemies.
She owns multiple beautiful and expensive horses over the course of the series, including Goldrush and Romeo, but is constantly having her parents buy her new ones.
Hester Brown is Amanda's sister and Issie's aunt who lives at Blackthorn Farm, near Gisborne.
(Issie did also look after Victory for a while until Natasha bought him from the horse's Tulia, but then things suddenly turn around when she is given the ride on him for Badminton.
Tara Kelly is a former four-star eventer mentioned in "Victory and The All Stars Academy" and "Liberty and The Dream Ride", and a major character in the Pony Club Rivals books.
In "Victory and The All Stars Academy", Tara comes to Melbourne to coach Issie and the Team through Cross Country.
In the books Tara is described as thin and slender with fine bones and glossy walnut brown hair, and she has a smattering of delicate freckles across her cheekbones.
Even though Tara is portrayed as cold and strict, sometimes her facade melts; she cradles Issie in her lap after rescuing her from a wild dog in "Victory and The All Stars Academy", and has several maternal moments throughout the series "Pony Club Rivals".
