Dirk Gently’s Holistic Detective Agency – Douglas Adams
This book by Douglas Adams is as crazy as The Hitchhiker’s Guide to the Galaxy. The only difference is that while Hitchhiker’s is completely crazy, Dirk Gently is crazy with a more organised plot.
Caves of Steel – Isaac Asimov
What I admire the most about Asimov is that if he sets a story in the future, he is able to add so much detail to it that it feels real and possible.
