Query: In Defense of Carson Napier

This was the first book in Edgar Rice Burroughs' "Carson of Venus" series. It was the last major series that ERB created, 20 years after he created "John Carter of Mars". In this book, Carson Napier builds a rocketship and sets out for Mars, but ends up on Venus. He has a series of episodic adventures, and falls in love with a beautiful princess along the way (which happens in just about every ERB book). Fun stuff, if you are a fan of this sort of thing.
