THE REVISIONISTS

More science fiction than mystery, Mullen's latest has a lot of depth. Narrator Robert Fass helps listeners along with his brisk narration and quick delivery. In a post-9/11 society, Dex, a time traveler from the perfect future, finds himself in conflict with the Hags, a group committed to head off wrongs before they happen. For example, the Hags tried to prevent the Holocaust. But Dex's masters believe that earth’s perfect future wouldn't have evolved without both positive and negative events having taken place. So Dex attempts to stop the Hags from fixing earth's injustices—and soon begins wondering whether he’s a good guy or a bad guy. Fass is especially plausible in the female roles and credible with the varied accents. When the action ramps up, so does Fass. It’s almost a perfect listen.
