This work will give you a brief summary of 100 SF novels. Of those I have read, I found the summaries (and the books included) to agree with my assessment. The ones I haven't read are on my "to read" list! (English 191 students will find my copy on reserve in the library. Others not lucky enough to attend Penn State Hazleton will want to order it!)
This novel is one of my favorites by a master of very funny SF( including the Hitchhiker's Guide series). Read all about the electric monk! If you loved the Hitchhiker's Guide, you'll love Dirk Gently.
The second novel of Le Guin's Earthsea Series, this book can also stand on its own. This novel about Sparrowhawk (Ged) and his adventures in Atuan. He frees Arha, the Eaten One, who serves old powers of darkness. It is Sparrowhawk who tells Arha her true name -- Tenar.
Anyone who enjoys reading SF stories will love this collection. It is also essential reading for any serious study of the history of science fiction.
