Book 4 of the Redwall series. This was a decent story that I had a hard time finishing. The reason is that it is the same plot line as the last three books. When I say the same plot I mean the exact same plot. It is like rereading the last three books. I am sure that others enjoy it, but it made it hard to get through this one. Aside from that it is well written and gives another chance to revisit the familiar setting.
