Age of Voodoo — James Lovegrove

Lex Dove thought he was done with the killing game. Then a call comes. One last mission: to lead a black ops team into a disused Cold War bunker on a remote island. One hundred feet below ground they face the fruits of an experiment in science and voodoo witchcraft gone wrong. As if barely human monsters weren't bad enough, a clock is ticking. Little do they know that deeper in the bowels of the earth, a god is waiting.

Lex Dove thought he was done with the killing game. A retired British wetwork specialist, he's living the quiet life in the Caribbean, minding his own business.

Then a call comes. One last mission: to lead an American black ops team into a disused Cold War bunker on a remote island. The money's good, which means the risks are high.

How high, Dove doesn't discover until he and his team are a hundred feet below ground, facing the fruits of an experiment in science and voodoo witchcraft gone wrong. As if barely human monsters weren't bad enough, a clock is ticking. Deep in the bowels of the earth, a god is waiting. And his anger, if roused, will be fearsome indeed.
