Putting faith in Paul Auster, the master of inventive perspectives and refracted truths, is a dangerously exhilarating proposition.  His story of innocence lost takes you around the world, across four decades, alongside all the players—and you’re still not sure whose side you’re on when it’s over.  The three rules to navigating Auster’s Invisible (Holt, $25) are: 1) don’t trust the narrator or any other characters; 2) don’t hope for a particular ending because that will ensure it won’t happen; 3) don’t believe in one Truth because everybody has his or her own version. Once you start this powerful mix of humanity and sexuality, you’re going where Auster wants to take you, and, as should be expected, it’s a dark, twisted place.  Have fun, and don’t forget the rules.
