It's ironic, i've read most of the novels, including all the Hohlbein novels and yet I remember so little of them now. I remember some specific scenes and situations but I can't really place them really well.
Of course it has been about six years since I read the last one but I do remember that I loved every one of them. Even Sky Pirates that a lot of people found really boring.
Now Hohlbein...what I do remember is that there are quite a few exciting and tense scenes in his novels. I loved El Dorado, but maybe that's because the myth itself is just so darn cool
The books mentioned in the opening post are definitly ones I recall as being one of the best!
It's time I started re-reading them I guess
