My retell

Thea Stilton and the mountain of fire

A flock of sheep at Nicky's family's Australian ranch was losing all its wool, and no one knew why. Nicky and her friends the Thea Sisters headed to Australia and set off on a tour of the whole country in search of clues. Nicky and her friends found out that their neighbor had poisoned the sheep's food. Nicky and her friends go on a search for family elders who know how to cure the sheep. Once they had found the elders they were told the cure was in Nicky's locket. Inside her locket was seeds you needed to boil and feed to the sheep. Nicky and her friends returned to the ranch and did exactly what the elders said. The next day the sheep's wool started to grow back. This was an adventure the Thea Sisters would remember.
