Seed — D.G. Leigh

Twenty-eight days meets the Triffids in a terrifying twist of nature. ★★★★★Humanity is doomed. A furious alien species of kilometre tall tree has taken root on Earth.Interlocking canopy branches rapidly block out the sun, plunging our planet into permanent darkness.Mind control spores infect the population, the masses assist with the continued spread of infestation and the elimination of resistance.Strangers Jo and Leslie rescued seven-year-old Susan as they fled the plague but now find themselves in even more danger, trapped and hunted. Unimaginably, among the dwindling survivors a shadowy faction implements their own play for world domination.The fate of mankind will ultimately be fought against more than just a single foe.
