Peter is hard at work training sheepdog Blue for the trials at the Ballynoe Fair, while Kate - who wants to be a vet like her mam - has her hands full taking care of her cheeky pet hen, Hettie. But a trespasser is nearby, getting ready to strike. Hettie and Blue can sense it - can they warn the humans in time?

The first book in the Hazel Tree Farm series, following the adventures of the Farrelly family, their neighbours, and a host of furry, woolly and feathery friends!
