In The New York Times Book Review, Sam Tenenhaus writes: "Jonathan Franzen's new novel Freedom, like his previous one, "The Corrections," is a masterpiece of American fiction." It is a great review; whether you should read it or not depends on how much of the novel you want spoiled.
In other Freedom-related news, President Obama apparently read an advance copy of the novel during his recent vacation to Martha's Vineyard. You may remember that former President George W. Bush read Albert Camus' The Stranger during his presidency - all 160 pages of it! But then, that is a novel about murdering an Arab.
