Rainbow Six

Two years ago, Executive Orders, which thrust Jack Ryan into the Oval Office, raised the bar for its immensely popular author. This first Clancy hardcover since then, though a ripping read, matches its predecessor neither in complexity nor intensity nor even, at 752 pages, length, despite a strong premise and some world-class action sequences. Instead of everyman Ryan, its lead is the more shadowed John Clark, the ex-Navy SEAL vigilante of Without Remorse who has appeared in several Ryan adventures. Clark now heads Rainbow Six, an international special-ops anti-terrorist strike force?and, despite the novelty of the conceit, that's a problem, as the profusion of protagonists, though sharply drawn (including, most notably, "Ding" Chavez, Clark's longtime protege), deprives the book of the sort of strong central character that has given Clancy's previous novels such heart.
