If there's an even darker side to Hollywood than the one America is familiar with, Bruce Wagner has found it. A twenty-first-century Nathanael West, he has been hailed for his powerful prose, his Swiftian satire, and the scalpel-sharp wit that has, in each of his novels, dissected and sometimes disemboweled Hollywood excess.Now, in his most ambitious book to date, "Still Holding," the third in the Cellular Trilogy that began with "I'm Losing You" and "I'll Let You Go," Wagner immerses readers in post-September 11 Hollywood, revealing as much rabid ambition, rampant narcissism, and unchecked mental illness as ever. It is a scabrous, epiphanic, sometimes horrifying portrait of an entangled community of legitimate stars, delusional wanna-bes, and psychosociopaths. Wagner infiltrates the gilded life of a superstar actor/sex symbol/practicing Buddhist, the compromised world of a young actress whose big break comes when she's hired to play a corpse on "Six Feet Under," and the strange parallel universe of look-alikes -- an entire industry in which struggling actors are hired out for parties and conventions to play their famous counterparts. Alternately hilarious and heartfelt, ferocious and empathetic, "Still Holding" is Bruce Wagner's most expertly calibrated work.
