Robbie’s in trouble! When his mum disappears he’s sent to Ireland to live with his maternal grandmother–someone he’s never met. Nanna seems nice enough, but she is always warning him about fairies, leprechauns, banshees, pookas and grogoch, insisting these spirits live in the forest near her cottage. Of course Robbie thinks she a little bit off her rocker, but when he meets some of the other unusual locals, he suddenly changes his mind.
