Paradise house - K M Peyton

When Alice Ticino's pony bolts and crashes into a family of strangers,
it changes her life. Before long, this lonely girl who has
never known love has been befriended by the family and - a dream
come true - is allowed to wander freely in their stables, where they
train racehorses for other owners. But Alice must stay away from
Snatchcorn, a beautiful stallion, so dangerous that it is soon
to be put down. Alice finds that she has a special bond with Snatchcorn.
Can she save his life by persuading his owner that he can
be tamed?
