Publisher's Synopsis
The gang have been hunting for Isabella for weeks, but there’s no sign of her in the Unlands. They can’t even find the portal through to Annwn. And Vivi hasn’t told the rest of the gang about what happened with the villainous Arawn appearing in her dream. She definitely hasn't mentioned how scared she is to fall asleep, in case he reappears. Even Nimue has been quiet. As much as Vivi wants to hope that it’s all over, part of her knows it isn’t...
On Dara’s birthday, an invitation comes from their cousin Violet; come stay on Bardsey Island for a week, stay at their cottage, and celebrate Halloween. And bring all your friends! Vivi can’t refuse an opportunity to go back to Wales, and her friends are immediately excited for star-spotting, foraging, hiking, and just general adventuring. Little do they know, they are about to be thrown into a huge high-stakes treasure hunt, with the fate of the world resting on them (again). And Vivi’s feeling that Arawn is just waiting to reappear is only growing stronger...
