Ponies from the Silver River – The Riding School in Danger

When a pony trek organised by their riding school ends in tragedy, Poppy and Scarlet find themselves right in the middle of an investigation. Strange things start happening, and it doesn't look like they are coincidences. Who has a grudge against the stables and wants to destroy them? Suspicion falls on the rival riding school, Claydon Manor, but is their ruthless manager really to blame?

To make matters worse, an unknown intruder lets Cloud out of the stables and he escapes onto the moors. Will the girls track down the unknown avenger before he can cause any more damage?
