In ''Roomanitarian, popular author, actor, musician, and spoken-word artist Henry Rollins returns to the combative prose that has won him critical acclaim and a legion of devoted fans. The book is divided into three parts: The first section, ''Walking the Chasm,'' written in the form of a poem, epitomizes Rollins's beautifully stark, hard-hitting style. The second part, ''Ended,'' is a series of short prose pieces reminiscent of ''Solipsist. Finally, the biting humor and social commentary Rollins is renowned for is on full display in ''To Ann Hitler with Love,'' a series of mock love letters to a fictional woman who bears a striking resemblance to conservative pundit Ann Coulter.
