I'm 13 and this was a great book for me, including the team - the following book in the series - and Blind Beauty by K.M Peyton. If, K.M Peyton is new to you I would recommend her to you because, she's great for children aged 10-14 even adults wouldn't mind her. She's great about horses and writes good plots.
This is a heart braking but tempting and loving book all in one about Ruth Hollis who really wants a pony but, her family don't have enough money. She meets a boy called Peter who helps her out and gives good friendship. Finally she finds a pony for a cheap amount. However, this pony doesn't behave and is really difficult and as Ruth's first horse this is her toughest challenge yet!
If you like a great book about horses, love, passion and adventure this is definitely the book for you and you seriously can't miss it!
