Guardians of Magic - Magic Crystals

Cakle — a mysterious mansion full of strange objects. But after years of peace, its secrets are awakening…
When Ava and her mum inherit a Victorian mansion, they have no idea that a great adventure is about to begin. Ava discovers a room full of peculiar curiosities and, inside it, a box of crystals. And when her mischievous dog, Pepper, tries to eat one of them, it triggers a chain of strange events that could change not only Cakle, but the entire town! With the help of her friends, Sarah and Lily, Ava must find out if three ordinary girls (and a headstrong little dog) can control the power of the crystals.
