Author Scott Sigler delivers an adventure on par with ‘Raiders of the Lost Ark’ but with a focus on anthropology instead of archaeology, and with a backdrop of mining instead a race for historic artifacts. Genre-wise the compare/contrast gets a little tricky. ‘Earthcore’ is present-day sci-fi horror, while ‘Raiders’ is… erm… historical… ah…? Your guess is as good as mine. (Historical-science-fantasy? How else does one sum up: “Fire. Lightning. The power of God or something.”) The point I’m trying to make here is that ‘Earthcore’ is every bit as compelling, as fast-paced, and the only thing it lacks is Harrison Ford.
