Robert Silverberg & Alvaro Zinos-Amaro 
When The Blue Shift Comes 

In the far future, Earth is about to be swallowed by a black hole in this sweeping SF epic from one of the masters of the genre.In a time so far from our own that we cannot comprehend it, humanity has spread amongst the stars and changed in more ways than we can count. But they have never forgotten their birthplace – Earth. But now Earth stands on the brink of catastrophe, at risk of being swallowed by a black hole. One man, Hanosz Prime, ruler of his world, is determined to visit Earth before it is destroyed. His abdication from his throne and his wanderlust are to prove the beginning of a much longer journey – one that will see him fall in love, meet the Oracles of Earth and perhaps, if he is very lucky, provide a means to save the cradle of humanity.Originally started by Robert Silverberg more than 20 years ago but never completed, Hanosz’s story is taken up by Alvaro Zinos-Amaro. Silverberg hand-picked Zinos-Amaro to complete the book, and provided notes and guidance. The result is a remarkable collaboration between one of the masters of SF and one of the most exciting new voices in the genre.
