Dead Reckoning — Tom Wright

Civilization is descending into the apocalypse: a deadly, extinction-level plague engineered by terrorists, international wars, and mankind's own innate depravity are about to take the world to the brink of collapse. Those are the last things Matt Anderssen, a scientist stationed at a Top Secret missile test site on a remote Pacific island, knew before all contact with the outside world suddenly stopped. Stranded on the idyllic tropical island that was his home and cut off from his wife and children by five thousand miles of ocean, Matt elicits the help of two loyal friends to find out what happened. Together, they defy the law and set out to sail across the Pacific Ocean to reunite with their loved ones -- if they're still alive, if anyone is still alive. High seas, zombie-like pirates, severe storms, and terrible luck will test them physically. Hopelessness, anger, self-doubt and the pure horror of the disaster will test them mentally and emotionally. But against all odds and with the help of a woman they rescue along the way, they will make it to the mainland -- and what they find there will be the ultimate test of survival. Stretching from a tropical paradise to the dusty, squalid streets of a third-world island across the vast Pacific Ocean to a tattered North America, Dead Reckoning is a post-apocalyptic story of a man and his friends who will stop at nothing to save their families and each other.
