Contaminated — Suzanne Robb

Dr. Arthur Covington may hold the key to the most important discovery in the history of humankind. He is, however, not the only interested party. If he is to survive treachery and attempts on his life in his bid to escape a secure, high-tech facility, he will have to rely on others - but who can he trust? Underground, an explosion rocks the facility. Someone drops a viral agent. In a new world where none can be trusted, Covington's life hangs in the balance. It's a race against time...and the end of the world...because it's not just the living he has to fight against. The dead are rising. Dead men walk the halls below the earth, and the only thing keeping him from being contaminated is his gas mask...and it won't last forever.
