Deadly Messenger - Earth Survives Series, #3

How Heroes are MadeSafely hidden on Able Island, Moses Zhang is ready to unleash thousands of virus-weaponized POE soldiers on the remaining rebels taking shelter in Freeland and in Raven's Park. The POE Army's deadly message-join us or die. A tiny band of Indies and Outlanders-Wren, Coru, Nelson and Dom-have secured the antidote to Zhang's Ebola Venus II virus, at great personal cost, but they're still trapped in New Pacifica.
In desperation, they split up, something they swore they'd never do, hoping one, at least, would escape the gang infested New Pacifica and reach Raven's Park and Freeland in time to replicate enough antidote to shield the innocent. Now is the time for every Outlander, every Freelander, every Indie to step up and be counted; for simple, humble people to join together to protect their families, their friends, their homes-to become heroes.
