The creative imagination of Hugo, Nebula, and Locus–winner Robinson (The Years of Rice and Salt
) is on display in this offbeat novel of scientific discovery. In 1609, a stranger tells Galileo Galilei about a recent Dutch device that magnifies distant objects. The Italian scientist develops his own version, and the success of his telescope brings him recognition and acclaim. Forty pages in, the book changes genres abruptly as the stranger brings Galileo to Europa, the second moon of Jupiter, in a far future where various factions quarrel over plans to colonize the distant sphere. During the course of several trips through time and space, Galileo becomes something of a pawn in the political conflicts while gaining treasured glimpses of the future of science. Readers will eagerly share Galileo's curiosity and astonishment at the wonders of both the past and the future. (Jan.)
