Doorways in the Sand by Roger Zelazny:
Science Fiction Inventions, Technology and Ideas
I admit it; I love this novel and I don't care who knows it (imagine sound of window breaking as rigid editorial standards are thrown out of it). This novel has a cool plot, a frozen uncle, undercover alien cops, acrophilia and a positively cosmic viewpoint of culture. All from the point of view of Fred Cassidy, eternal student. Select
