When the blue shift comes

One of the greatest stories I've read. Some authors devour concepts, others characters and few great authors indulge in twists of the plot. How would it be if all three gets together and on top of it, written by two authors, interconnected by a time interval that spun over two decades -- this is the novel, or more specifically novella-couplet.

The story revolves around what happens during the end of the universe and dwells into the concept of parallel universes, time dilated events while trouncing on the concepts that make our lives, the impact of parent-child connection, of self realization while preaching a small philosophical adage that being in peace with oneself is the best a man's singularity can experience.

A must-read, especially the icing on the cake that is the final chapter.
