Aggie Lichen faces the same dilemmas as any other thirteen year old; what to wear, how to keep out of trouble at school. But while other thirteen year olds are doing their homework or settling down to watch T.V., Aggie flits from house to house in search of prize pilps. That’s where Aggie is a little different. You see, Aggie Lichen is a pilp collector - a tooth fairy!
One nightsgritch - a tooth collecting evening - Aggie is attacked by a bright, mysterious light. Is it just a low flying glow-worm or a bad-tempered giant bluebottle? Or, as Aggie and her gang suspect, is it something more sinister? Unknown to them, Aggie and her gang have just thirty days to solve the mystery and save their kind but time is not on their side... neither are the sprites or the Grublins.
