This (part 4)

Time is running out. After their narrow escape from the besieged Citadel, Rietta and Carla must finally fulfil their promise to the Fair Ones. Using powerful magics stolen from the Elfyn empire, they seek to protect the Three Realms by reciting an ancient and dreadful spell... They soon learn that things are not as they expected. As hopes of their safe return home are consumed in fire and darkness, the girls realise that there are dire consequences. Now, more than ever, they must rely on each other and the magical friends they have made on their journey. But is everyone who they appear to be in the final, thrilling instalment of 'This'?'This That and the Other' is imaginative fantasy, on an epic scale. The story follows the special friendship between two girls who embark on a magical adventure together, across the three realms. It is a modern fable inspired by fairy tales and folklore whilst remaining relevant to today's most important issues, in the tradition of 'The Neverending Story', 'The Box of Delights', 'The Chronicles of Narnia'...
