The Almost Exmoor

Nine-year-old Samantha has some questions.
When is an Exmoor Pony not an Exmoor Pony? What will her twelve-year old sister, Emily, do now she's grown too tall for her pony?
Can she deal with taunts and lies from Mia whose pony is on the same Yard?
Gemma, Samantha's friend, would love her own pony, but how can her Mum ever afford one?
Samantha finds the answers - if she can only get the adults to agree. But one plan leaves Emily just three weeks to prove she can cope with Sunny, the lively young Almost Exmoor.
Then there's another question - can the family prove Sunny is a proper Exmoor pony? But if they do will her owner insist on taking her back?
It's a tough time for Emily!
