First the fairies took Tam's little sister, Blue. Then they took his Great-Grandpa Toby. Now Tam has to keep a great secret - not only is Great-Grandpa still in Faery as King, but the old King of the fairies, Oban, is now in Tam's world disguised as a boy Tam's age! At first, it's lots of fun having Oban and his magic around. He manages to charm everybody - even Tam's teacher at school. But then things start to go wrong ...When Tam finds the magical Windspinner that Great-Grandpa Toby left for him, Oban can't make the magic work like Tam can and he disappears in a huff and starts causing chaos. The only person who can stop the trouble and call Oban home to fairy land is his mother, the Damson Hag. But she's locked up tight in a golden cage. So Tam sets off on another adventure to Faery - this time with Great-great aunt California at his side - to rescue the Damson Hag and try and return Oban and Great-grandpa Toby to their right homes... - from Amzon
