Book excerpt: There are shortcuts through spacetime from one part of the universe to another. The trouble is you can never be sure what's at the other end of one or going to come through one to visit you. Suppose you make contact with aliens - can you be sure you can trust them? Or could they be tricking you into doing something which would be disastrous for you but which they'd find hilarious? Then there's the temptation of time-travel. It seems so simple to nip back into the past, alter a few things to make your present life exactly as you'd like it to be. Unfortunately there are always unforeseen consequences and things never turn out as you hope. Also space travel is more complicated than you expect because time goes at different speeds depending on how fast you are travelling. So your journey may only take a year but when you get back everyone else could be a century older. Nothing but problems - but entertaining for those who like sci-fi stories like the ones in this book. Have a good time...
