Die Clawdius — Robin Price

In the third installment of the series, six-clawed hero Spartapuss is horrified to find that the Emperor is planning an invasion of the Land of the Kitons, aka Great Britain. Clawdius, the least likely emperor in Roman history, needs to show his enemies who is boss. While Spartapuss has always wanted to visit his birthplace -- famous for its terrible food, evil weather, and the tuneless howling of its savage tribes -- he is loath to journey there as part of an invasion. However, he soon finds himself rounded up and forced aboard the first ship in the invasion fleet and part of the landing party that sets out to search for the Kiton Army. Soon captured by two warriors, Spartapuss manages to escape into the woods, where he meets Furg, a young Kiton studying to become a Mewid. After joining her at Mewid training school, Spartapuss realizes he must choose between his new friends and the Emperor. Can the magic of the Mewids help him make the right decision?
