Welkin Weasels (2): Castle Storm

Sylver's search for the elusive humans - their only hope - leads him and his intrepid band of weasels to an enormous ruined castle, deep in the heart of the bleak flatlands of Darkmoor. Here he meets Clive of Coldkettle, the leader of the red squirrels - who are in a state of permanent war with the grey squirrels.
