Monster Island by David Wellington, 282 pages

Dekalb is with the UN as a weapons inspector in Somalia when the zombie outbreak hits the world. Somalia, due to the large number of guns in the hands of the general population and lack of stable government has survived better than many large nations. He is given the chance for him and his daughter to have a decent life if he can track down medicine for the local warlord. The best chance for finding it... New York City. But New York City is completely overran. Can Dekalb make it in and out with the medicine, and his life?

This was a great entry in the zombie genre. I can't believe I've never read it before. I've got the other two checked out and can't wait to read them.
