Journals of the Damned by GJ Zukow
When the genetically engineered single celled parasite Toxoplasmosa Mondus Omni is released upon the world, nothing will ever be the same again. It starts by moving like wild fire through the animal kingdom, killing them by the billions and driving them insane.
Then it mutates and sweeps through the human race who have no immunity to this man made horror.
As if this new plague isn't bad enough, sickening and killing people after driving them mad as it had in the beasts, it brings with it something truly terrible...
It raises the dead , with a cannibalistic hunger, to hunt down the immune.
These are the journals of two desperate survivors that have been recovered from the time of the Apocalypse.
