Those two books absolutely enchanted my eldest during the period-of-restricted-freedoms-that-shall-not-be-named, and I loved reading them aloud.
They had that quality of transporting you to another place which some adventure tales aspire to, but don't quite reach.
They strike me as quite unusual, but it might be that there are comparable books I don't know about.
Can you recommend anything similar - animal characters, a dash of the surreal and mystic, heroic plot?
Any leads welcome
