Ship of Strangers by Bob Shaw

Good

The chronicle of adventures of the survey ship
Sarafand as it journeys through space exploring
and mapping newly-discovered planets.
The mission brings them into contact with many
startling life-forms and menacing aliens. On one
world the Sarafand sends out six survey modules
and seven return ... one of them is a shape-
changing, malevolent alien - but which?
On another planet they discover a humanoid
civilisation which can move around in time.
Suddenly the Sarafand investigators are marooned
millions of years in the past.
Finally, the Sarafand and its crew are stranded in a distant galaxy where everything - including them -is shrinking inexorably to, zero size ...
`Top flight space adventure ... Shaw's control is
immaculate and his action supercharged. Use it to
