The first chapter of Deathworld is posted as an audio book below this blog.
Harry Harrison is one of the best Sci-Fi writers of all time. His imagination in his storytelling, his ability to drive a story successfully to an exciting conclusion were amazing. He took me more places as a child than just about anyone in my youth did.
Science Fiction has become a lot more cerebral these days and his writing remains more in the tradition of Edgar Rice Burroughs, who was, in my mind, the greatest of Fantasy writers alive at the time and maybe even now.
Best to all and enjoy.
