Few forms suit SF better than the short novel: long enough to flesh out the details of an alien world or bizarre future society, yet short enough to pack a punch - powerful, elegant and free of padding.

Now, drawing on his benchmark annual series Best New SF, multiple award-winning editor Gardner Dozois selects the 13 finest science fiction novels of the last 20 years.

These unmissable tales, collected here for the first time in one volume, include:

Robert Silverberg's 'Sailing to Byzantium'.

Michael Swanwick's 'Griffin's Egg'.

Alastair Reynolds' Turqouise Days'.

James Patrick Kelly's 'Mr. Boy'.

Ursula K. Le Guin 'Forgiveness Day'.

Greg Egan's 'Oceanic'.
