Hex Vet: The Flying Surgery [PDF ebook] 

It’s time for the monthly "Winged Creature Clinic" at Willows Whisper Veterinary Practice, where flying creatures from all over come to get treated. But when Glenn the Wildlife Warlock brings in an injured flying pig that looks like it may have been mistreated, panic strikes and a greater mystery unfolds. It’s up to everyone’s favorite vet witches in training, Nan and Clarion, to keep everything under control at the chaotic clinic while Dr. Talon is away. Will Nan and Clarion save the day and keep their jobs? Or are their days at Willows Whisper numbered?
