Safari - more zombie killing with your favorite alcoholic

Book two of the Mountain Man series picks up right after book one as Gus recovers from the attack on his home that almost killed him. His poor state of health forces him to venture into the city to find pain killers to aid in his recovery so he makes sure to also grab supplies (mostly booze.) WHen he begins to feel better he decides to take advantage of the winter conditions and fight back against the zombie horde down in the city while the cold and snow hampers their movement. This leads to the advancement of one of the more intriguing threads from the first book - why do the zombie corpses completely disappear within a few days after they are killed for good? When Gus finally uncovers the root cause behind the disappearances, he finds himself facing a new threat even more menacing than the zombies themselves.
