Rumors of a secret 'ace' among the delegates to the 1988 Democratic convention threaten to undermine the 'jokers' rights' movement espoused by charismatic politician Gregg Hartmann. The latest installment in the popular 'Wild Cards' series offers nonstop action and an emotionally appealing group of superheroes (and supervillains). Explicit sex and graphic violence, however, may limit its general appeal. Recommended where the series has a following. Copyright 1990 Reed Business Information, Inc.
