The Ice Chasm(Harvey Bennett‪)‬

A door in the ice is discovered in the middle of nowhere in Antarctica.
And it just opened . . .
Hidden beneath a sheet of ice, Draconis Industries has been working on a powerful new technology.
Harvey Bennett and his new team are sent in to shut them down, but what they find inside is far more sinister than they could have imagined.
Worst of all, an army of Chinese soldiers-hoping to get their hands on the tech-are at their heels.
