content: Every once in a while, I pick up a book thats tough to put down. I read this one in several sittings and as I read, I kept thinking of what a great film it would make. I make this statement because the novel is very visual, has a great cast of characters, and a story line with a interesting perspective on the first manned Mars mission. I like my Science Fiction with a heavy emphasis on science and technology, and this book delivered. I found myself deeply involved with the characters, and their situations as well. The last few chapters, especially the epilog, brought a tear or two to my eyes. I highly recommend this novel.
