The unpredictable Penny Pollard is back and this time she's loose in England. Accompanied by her friend Alistair and his mother (the long-suffering chaperone), she looks for the Loch Ness Monster, discovers a new and not-so-mysterious meaning for Stonehenge, and makes lots of new friends from all over the world (including the irritating, maddening, kleptomaniacal Heidi). Somehow, between adventures and sightseeing, she finds time to write, and her personal diary, letters, miscellaneous notes and snapshots have all been preserved for posterity and to the delight of would-be rebellious heroines everywhere.
