Although this is a satisfactory sixth sequel to The Animals of Farthing Wood, it is not of the same standard as the other books in the series. It was published in 1992 and seems to be an afterthought by Colin Dann, as by then he had written 7 other books which were not in the Farthing Wood series such as 'A Great Escape' which were fresh and exciting. Perhaps, the publishers wished him to return to the Farthing Wood well again but it was virtually dry. For completists it is a must and it has attractive chapter header illustrations by Trevor Newton. However, the animals that have survived all the previous adventures are unnaturally old and Dann attempts to address this by including animals such as Dash (the grand-daughter of the original Hare!) and Plucky who is a direct descendant of the original Fox who is still alive. The story involves the creation of a new reserve by the warden and an invasion of White Deer Park by a colony of murine mammals - rats!!!
