Roger Zelazny is one of my favourite authors. He writes well, with humour and quite astonishing invention and has earned several top SF awards. Doorways in the Sand is not one of his best but is still very enjoyable reading, with a mysterious alien artefact, galactic cops and robbers, lots of excitement and plenty of humour. Pure escapism—and I loved it!
