When Superman debuted in Action Comics back in 1938, he had remarkable abilities, but wasn't the God-like mover of planets he became in the Silver Age. His strength while an infant caused bit of a ruckus during a brief stay at an orphanage, but he didn't take up life as a superhero until adulthood. Phrases like "able to leap tall buildings in a single bound" and "nothing less than a bursting shell could penetrate his skin" applied to Siegel and Shuster's creation, and his powers only increased gradually over the years. Tom De Haven's novel tells the origin of a Superman who's much closer to this original version, and set in the same era. However, it's also set in a world closer to the real one than usual for Superman stories, with New York subbing for the fictional Metropolis and aspects of 1930's America observed that would not have appeared in early comics. Lex Luthor has a rather different career here, one that forces him to deal with several historical New Yorkers well before he encounters Superman. I think these changes work very well, and make the book read more like a true novel than a novelization. There are also numerous little surprises to amuse hard-core Superman fans. (I don't want to give away too much, so let's just say it helps if you know the name of the artist responsible for the iconic look of the Golden Age Superman.) I can't quite give this novel five stars, as the plot meanders a wee bit too much in places, and I think ultimately any novel treatment is going to run into limits on how well it can deal with a character invented for graphic portrayal. Still, "It's Superman" is far more satisfying than anything along these lines that I've read before.
