Northmead Nuisance

This is one I don't have yet, Northmead Nuisance, the second book about the school in Kent. I really enjoyed New House at Northmead and hope this book is up to the same standard. Most people who have written to me about it seem to think it's a pretty run-of-the-mill story. But we shall see... The only problem about this book is its price: the cheapest copy I've found is 170 GBP. But I'm hopeful that I can come across a better deal during my trip to the UK next month.
