Like "Kage Baker on steroids," says David Hartwell in his promotional letter, and indeed Asher's latest SF novel (after 2004's The Skinner
) bears definite similarities to Baker's popular tales of the Company. Both involve near-immortal time travelers who pursue complex, often mysterious objectives. But where Baker tends toward the literary and satirical, Asher prefers over-the-top violence and pyrotechnic super-science. In the near-future, Polly, a prostitute, and Tack, a government-programmed killer, get caught up in a war fought by superhuman antagonists from the future, the Heliothane and the Umbrathane. Neither side is particularly sympathetic, but the latter group is allied with the monstrous Cowl, an even more advanced being that threatens all human life. Cowl has let loose the torbeast, a ravening interdimensional creature the size of a small planet, and the Heliothane have reprogrammed Tack to go back in time and assassinate the monster. Well-done battle sequences, serviceable characters and an old-fashioned sense of wonder help offset a sometimes overly byzantine plot and a too-abstract depiction of time travel. Overall, this is an excellent read and should increase the author's growing reputation. (May 18)
