Our family has been enjoying the first three audio books in this series very much. At this time, most of the stories have been produced in this audio format. The Silver Chair will be made available this spring (2002) leaving only the Last Battle to be produced. The narrator, Paul Scoffield (A Man for All Seasons [1966] and Hamlet [1991]) is just excellent. While the stories are somewhat abridged, they are remarkably complete for an audio drama.
