On a remote island deep within the Arctic Oceans of the North Pole there's been a fantastic discovery: an ancient eskimo village has been uncovered beneath the ice. It could be the archeological find of the century.
Professor Henry Jones is heading up the expedition into the frozen wasteland and he's brought in a former student to help him out: Jacen Castle. And where Jacen Castle goes, his nieces, Faith and Summer, are never too far behind.
But what starts out as an adventure in uncovering the past, quickly turns into a struggle to stay alive as Agent Dark and the Tancredi Group make their next move.
Trapped in an arctic wasteland, it'll be up to the Castle Sisters to save the day, or face certain doom!
And if you haven't already, why don't you go ahead and pick up the first book the series:
