Taking place in the kaleidoscopic future of Ian McDonald's
highly-praised Desolation Road, Ares Express is set on a
terraformed Mars where fusion-powered locomotives run along the
network of rails that is the planet's circulatory system and
artificial intelligences reconfigure reality billions of times each
second.
One young woman, Sweetness Octave Glorious-Honeybun Asiim 12th,
becomes the person upon whom the future - or futures - of Mars
depends. Driven away from teh locomotive that has always been her home
by the thought of a boring marriage and an all-consuming wanderlust,
she consults her dead twin, Little Pretty One, about her future. But
that future will take in religious cults, artificial intelligences
that are as gods - and the gods themselves.
Big, picaresque, funny; taking the Mars of Ray Bradbury and the
more recent, terraformed Red Planets of authors such as Kim Stanley
Robinson and Greg Bear, Ares Express is a wild and wooly
magic-realist SF novel, with many bizarre philosophies, strange,
mind-stretching ideas and trains as big as city blocks.
