A year ago, Trina and Mark survived the sun flares--the worst natural disaster known to mankind. But what came after was even worse: tsunami, solar radiation, drought, incessant heat, and pure anarchy. Together, they battled through one life-threatening obstacle after another. Just when they dare to hope that everything is going to be okay, their settlement is attacked by strangers wielding virus-infected darts. Now they must escape this madness-inducing deadly disease. Along the way they find evidence that there may be a cure. But will they be able to reach those who unleashed the virus before they cross the boundary into madness themselves?
