Golden Witchbreed is astonishingly good. If you have not read it, you should first read Ursula LeGuin's The Left Hand of Darkness, the archetypal SF novel of an ambassador to an alien world where the people seem like us, but are not.
The ambassador here is female and her blonde hair is enough to make the superstitious dark-haired people she meets suspect that she is one of the previous ruling class, the golden witchbreed as they are now known. These aliens are derived from reptiles and still reproduce by laying an egg which the male incubates in a pouch, though the delicate nature of her mission means that the ambassador is afraid to ask right out about reproduction or other personal matters. Instead she travels from place to place around the world of Orthe, observing, experiencing the climate and culture until, like LeGuin's ambassador, she finds herself receiving unfriendly attentions.
The planet is very well described and we really feel what the characters do and fear for their lives. Read it. The second book Ancient Light is also good but ends unhappily, I warn you.
