Divide & Multiply is volume two in the EVIL VEIN trilogy. The killer infestation continues to spread beyond the confines of Tylerton. The reanimated zombie corpse of scientist HAL JOHNSTON is washed up on a populated San Diego beach to infect all who comes into contact. Flamboyant MARCEL DOMINGUEZ flees for his life and finds shelter in an old time radio station built by VINNIE COBB, a Vietnam veteran and conspiracy theorist. South of the border in Mexico's Rosarito Beach, HAL's Blue Gem Serum infects a new generation of scrabions, stronger and faster, with the collective consciousness inherited from the first mutants making them an unimaginable foe. One sting or scratch kills and turns humans into bumbling zombies. American twins CARRIE ANNE and KAYLA WHITE are trapped by the attacking scrabions as they try to get back to the border. Meanwhile in Tylerton, the scrabions are hibernating following the aerial blanket bombing of a bright red viral cocktail by the military, an attempt to attack the scrabions' DNA. The survivors we met in Dark Beginnings (Vol. 1) are still fighting off the zombie hoard. They are joined by newcomer CHRIS NGUYEN who knows of a fallout shelter at the top Weiss Road with food and medical supplies. They will be safe there ..........if they can make it.
