Pirates of Venus
Decent pulp sci-fi, but a bit too similar to the John Carter of Mars stories to make it seem like anything special.This is the start of the Carson of Venus series. After his spaceship misses Mars, it avoids crashing into the sun by luckily crashlanding on Venus.
Fortunately, the air turns out to be breathable, and the planet inhabited by humanoids.
There's another falling in love with a Princess story in there, as well as becoming the leader of a whole bunch of the natives.
