Delphinus — Michael Kingswood

Piter's honeymoon was off to a splendid start. He and his bride had a fancy bridal suite on a luxury spaceliner, and had their own private view of the most beautiful aurora in the known galaxy. Then it all went to hell. Narrowly escaping the spaceliner's destruction in a cargo shuttle, he, his bride, and five others crash onto an un-colonized moon, where they have to figure out how to survive until the rescue comes. Assuming it ever does.
