Donald can see ghosts - and talk to them. His friend Merry can just about make them out. His mum is a clairvoyant, and is sometimes hired to talk to ghosts to put them to rest. His dad is dead - but lives on as a ghost in a big house in the woods playing records.
Donald's mum hears word that there are ghostly goings on on the South West coast, so Donald and Merry accompany her to a caravan holiday park to investigate. Unfortunately, the rather unpleasant boy Danny also turns up there with his family and latches onto them. They also encounter the scary Estella, a very clever medium, who hatches an evil plan to get rid of the ghostly monsters once and for all. Donald finds himself in a life threatening situation - how will he get out of this alive?
This is a very funny story for about 10 year olds - Ally really gets you giggling on each page. Sometimes the writing and the story is a little loose and haphazard, but overall I really enjoyed it. I also loved her last book - Midnight Pirates.
