Starfire

High-tech hard SF and murder mystery converge in Sheffield's (Aftermath) latest, multi-voiced narrative, but the result does credit to neither genre. After escaping from the ""judicial sleep"" in which he was to have spent six centuries atoning for killing 18 adolescent girls in order to clone happier versions of them, infamous murderer Oliver Guest hid in an Irish castle. More than 11 years later, in 2053, Guest, still on the lam, is found by Seth Parsigian, who blackmails him into helping to identify a serial killer who has been slaying teenage girls on Sky City. The murders are upsetting the city's dedicated residents, who are building a shield to help Earth survive an oncoming wave of deadly particles from Alpha Centauri. While U.S. president Celine Tanaka handles the political fallout from physicist Wilmer Oldfield's disastrous predictions about the proximity of the approaching particles, Gordy Rolfe, the short, depraved genius who is in charge of building the protective shield, sabotages Earth's plans for survival so he can rule the depopulated planet that will be left in the wake of the disaster. Though there is plenty of action--the murders are solved, a love affair begins, evil characters are vanquished--the many switches in points of view produce a herky-jerky narrative, and there are long, dull expositions about particle waves and space stations. Sheffield creates powerful space-faring women, but his dark wit sparkles most in his depiction of Oliver Guest, who is rewarded for his crimes by having a houseful of loving little girls always at his beck and call.
