Publisher's Synopsis
Here, from the other side of time, come:
THISTLEDOWN, the asteroid starship of a future that is not quite our
future;
GAIA, a parallel reality where Alexander the Great's empire has ruled for
two thousand years;
and
THE WAY, an infinite corridor through space-time which traverses and
encompasses whole universes.
And as the strands of these mysteries are unravelled, so the ordering and the end of mankind -- and our entire Universe -- come into question
