Most people think that dragons and unicorns don't exist outside of story books - but Kat and Rosie know better! The best friends have been helping out at Calico Comfrey's Veterinary Surgery ever since they stumbled across its secret door one summer holiday. Join them as they rescue and care for the incredible, enchanted creatures of Starfall Forest. Along the way, they might learn some valuable lessons about bravery, friendship, and loyalty!

When Kat needs something to distract her from her new baby sister, it's the perfect time to go exploring in the forest. She and Rosie find a baby gem dragon coughing and spluttering in the Crystal Caves. What has made her whole colony so sick, and could it have something to do with the gnomes' new mining machines? It's time to start an anti-pollution campaign - with just a little help from Dr. Hart!
