Penelope Rose thought a cruise through Southeast Alaska would be a relaxing way to celebrate getting her degree with her friends. She couldn't have been more wrong. After a week of sun, fun, and visiting all the little attractions that every town had to offer, all that was left was a week at sea. Then came to request to stay in their rooms. Hours turn to days, and the food deliveries stop. Penelope and her friends have to leave the safety of their room, only to find most of the ship's passengers dead, or infected with a disease so terrible that Penelope can't even think the name.
