E. M. Forster 
Howards End [PDF ebook] 

Howards End is a masterful discussion of changing social class-consciousness. Three families from different levels of society become intertwined: the rich capitalists, the intellectual bourgeoisie and the struggling poor. Forster does not suggest that relationships between the classes are easy, but he does think them vitally important. The social philosophy inherent in the novel is significant and beautifully written.
