Tom, Minna and Finch are not your average children and the enormous hollow oak tree they live in is the oldest tree in the whole forest. It was their grandfather Beany who made it into a tree house with proper windows and doors and furniture. Beany is a magician . . . not a very good one, perhaps, but quite famous locally. Tom is the eldest of the three and likes to keep an eye on things but Minna, as the only girl,often takes over in a tricky situation and Finch, the youngest, often gets into scrapes. Sometimes they shoot off on an adventure together and sometimes one or another becomes involved in an unforeseen escapade that may be scary, may be hilarious, but is always exciting and packed with adventure and fun!
