The Jillies is the name given to themselves by the Jillions family.
The series starts on a holiday to Norfolk where the Jillies meet the
Standing brothers. After a shky start they become firm friends.
Subsequent books explore different locations including Austria.
The Luck of Sallowby is a particularly interesting story in
that it not only explores a real location, it also documents the real
events associated with the great Fen floods of 1947.
