CNN’s Anderson Cooper, one of the most respected voices in TV news, will be available live to interact with local audiences in a virtual setting to discuss his new book “Vanderbilt,” a portrait of one of America’s greatest dynastic families (which, of course, happens to be Cooper’s family as well). The online event is sponsored by Bookshop Santa Cruz. $33 gets you a ticket for the event, a copy of the book and maybe a chance to ask a question to Cornelius Vanderbilt’s great-great-great grandson. Things get started at 3 p.m. Friday.\
