This was the first Redwall book I ever read back in the 1990s, it was always my favourite. I got the chance to get the audiobook and it stands up. The cast of voice actors make the variety of accents easier to understand - and the different characters ea ier to differentiate - than the phonetic writing ever did for me, which is just an overall improvement. 

In terms of the plot, Jacques has several threads that mostly stay separate, until Book Three (the final third of the book, which is divided into three smaller books). The primary two are the Salamandastron plot thread and the Redwall plot thread, a siege and a sickness, and the threads that draw them together: villainous characters and mysterious places. Trust and friendship are forces that triumph over greed, malice and mistrust, but not without a price.

Well worth the reread.
