Publisher's Summary

Dive into adventure in the last unknown territory on Earth - the sea. Join Robby Hoenig and a cast of characters as unusual as any ever met on a distant planet...
In the second Robby Hoenig adventure, Secret under Antarctica, a scientific expedition becomes a race to stop a terrorist plot for world-wide disaster, buried beneath the ice of the South Pole...
