It is some time after Ed Chianese's trip into the Kefahuchi Tract. A major industry of the Halo is now tourism. The Tract has begun to expand and change, but, more problematically, parts of it have also begun to fall to earth, piecemeal, on the Beach planets. We are in a city, perhaps on New Venusport or Motel Splendido: next to the city is the event site, the zone, from out of which pour new, inexplicable artefacts, organisms and escapes of living algorithm - the wrong physics loose in the universe. They can cause plague and change. An entire department of the local police, Site Crime, exists to stop them being imported into the city by adventurers, entradistas, and the men known as 'travel agents', profiteers who can manage - or think they can manage -the bad physics, skewed geographies and psychic onslaughts of the event site. But now a new class of semi-biological artefact is finding its way out of the site, and this may be more than anyone can handle.

作者 M.John Harrison 憑藉本書(有譯<<新星鏇轉>>)獲得2007 Arthur C. Clarke Award(阿瑟·C·剋拉剋奬)另外,好象還是BSFA的入圍。

注: 阿瑟·C·剋拉剋奬每年奬勵上一年在英國齣版的最佳科幻小說，是英國最有名望的科幻奬項。該奬在1986年設立，第一位獲奬者在1987年被選齣。此奬由英國科幻小說協會和科幻小說聯閤會共同管理，它們每年提供兩位評審者；最近，科學博物館也加入該奬，每年提供一位評審者。
