Stories le plus cher at the Edge of Time by Robbins, Alan NEUF

A family on the last starship finds that stories themselves may very well save a dying world. A man finds a new lease on life in an ancient dingus. A phone that can be used to call a few minutes into the future leads to unexpected turmoil. An anthroid on trial for a murder may be the victim of a faulty linguistic circuit. A retired astronaut who cannot get his footing, the last librarian on earth, tales of longing spacefarers, and a mathematician whose brilliant insight continually slips his mind.
These are just a few of the themes to be found in this collection of mystery science fiction tales in the speculative tradition from the author of MazelTales: A Family Album, A Small Box of Chaos, and the award-winning An Interlude in Dreamland.
