This is a major shot in the dark, but in the 80's, I read a book about 5 or 6 youths who wake up on a deserted planet after their ship crashed. There were these worm like monsters that lived there. One of the five character was this bad guy who was real thin and gaunt, but very powerful. The ground was soft and springy. And some of their crew was killed in the crash. That is about all I remember. And this wasn't Dune! It ends with the main character beating the bad guy, and was set up for a sequel. Help me out here!
