ON THE STREETS OF fictional Elk River, Ill., a strike against Pentron-ics Systems, the town's largest employer, threatens to turn violent. Belowground, John Fortunato, a former Vietnam War "tunnel rat," has re-created his nightmare of combat in miles of meandering tunnels, where he obsessively replays the death of an Army buddy.
Fortunato reluctantly joins the action aboveground when his uncle, a union organizer, is killed. The veteran, joined by union lawyer Jill Baxter, focuses suspicion on Pentronics owner Anthony Hunt, a corporate predator with plans to sell out the business—and the town.
Flynn is up to more than old war games in this deftly mapped thriller: Digger carries a more disturbing, and deeper, message. Readers will dig it. (Bantam, $22.95)
