Roughing It — Elizabeth Black

When a strange outbreak occurs at a lakeside campground, Jake Walker and Lance Cameron investigate. Not only are they biologists, they're lovers who share a passion for science. The outbreak has locals terrified. Nine campers become sick; four die, and one victim reports an increase in her sex drive so serious, she attacks her best friend's husband. Is this lustiness caused by the disease? What's behind the odd rainstorm that falls over a small geographic area and the strange red dust around the cabins? Is this outbreak a new disease or something much more dire? Together Jake and Lance must find the cause before others are infected ... and before they come down with the plague themselves.
