The Sword and the Mirror

When Fiona discovers that fairies (sorry - nature spirits) actually exist as sentient beings riding the minds of insects and animals, she has no idea that she and her family are about to be catapulted into parallel universes where myths take on a new reality, and an evil sorceress has been bent on revenge since the time of King Arthur and the Sword of Justice... Fiona and her brother Tim embark on an epic journey to save their youngest brother, but little do they realise that they are about to join battle in a war that could decide the fate of the Multiverse!
