《水上之旅：探索水生生态与人类和谐共生的蓝色世界》littlesubgirl

　　When a local ranger in a small country town finds an unidentified algae overwhelming the town's water supply, he knows something's not right. But it's not until the sun goes down that he discovers the true extent of the danger - it seems the town is about to experience the effects of a mysterious infection that turns not only humans - but animals too - into zombies.
