<DIV>To understand Africa, one must understand Nigeria, and few Americans understand Nigeria better than Karl Maier. <I>This House Has Fallen</I> is a bracing and disturbing report on the state of Africa's most populous, potentially richest, and most dangerously dysfunctional nation.Each year, with depressing consistency, Nigeria is declared the most corrupt state in the entire world. Though Nigeria is a nation into which billions of dollars of oil money flow, its per capita income has fallen dramatically in the past two decades. Military coup follows military coup. A bellwether for Africa, it is a country of rising ethnic tensions and falling standards of living, very possibly on the verge of utter collapse ? a collapse that could dramatically overshadow even the massacres in Rwanda.A brilliant piece of reportage and travel writing, <I>This House Has Fallen</I>looks into the Nigerian abyss and comes away with insight, profound conclusions, and even some hope. Updated with a new preface by the author.</Div>
