Sub-Zero Survival

Join the Ripley's Bureau of Investigation - a group of teen agents with special gifts - as they embark on a series of action-packed adventures, travelling the world in pursuit of extraordinary events and tales. These wonderful new stories are perfect for adventurously minded children between the ages of 7 and 11. In "Sub-Zero Survival", the culmination of the first "RBI" series, the team begin to link together the hidden clues that they have found on their last few missions and the results point them toward Antarctica and an ancient ice station. However, terrible blizzards, floating pack ice, and a creature that swims with the seals make their hunt for a lost artefact anything but easy!
