Verona Rupes, on the ice moon Miranda, is the tallest cliff in the solar system. If you jump off the top, it takes 700 seconds to reach the bottom. What can you do in the most important 700 seconds of your life? Jonathan and Gaby arrive at the ice moon Miranda to work with a local researcher and find that adventurists have snuck into an area infected with alien bacteria and have gotten themselves in trouble. Do these people have to be stopped because they're about to spread a bacterial infection to the human settlements or are there other factors at play? A tale of petty vindictiveness, competition and jealousy. Oh, and a wedding.
