Greg Rosanoff and Rhonda Klimpt, seventeen, orphans and lifelong companions who live with their foster mother, stumble upon two rings in their hometown of Camas County, Washington.

The rings aren't ordinary rings. They have the power to grant flight, form protective shields, and more. Greg and Rhonda decide to use them to right a few wrongs and help the police oust evil in their city. Call it simplistic. That is what they want the most.

However, problems exist insofar as the local law doesn't exactly trust them. Moreover, the alien presence that created those rings—a being called Narsak—returns to Earth to claim his inventions.

Things are never as they seem, and Greg and Rhonda find themselves battling public opinion as well as the alien who seems to toy with them. They must find a way to defeat Narsak or else Earth will cease to exist. In a showdown on an active volcanic field, Greg and Linda prepare to face off against an implacable foe and even give their lives, if necessary.
