Amazon Swamp Victory - Gerard Doris - Bog

The Treasure Rebels are taken to the Amazon Rainforest and forced to search for a priceless dive helmet hidden in the murky depths of a jungle swamp. A swamp that contains electric eels, other incredible dangers, and the rusted underwater ruins of a destroyed steamboat.
With their lives on the line, the Rebels set out to not only outwit their enemies and locate the helmet, but to find the answer to a legendary mystery more thrilling than any treasure hunt. "Amazon Swamp Victory" is the third adventure in the Treasure Rebels novella series, and directly follows the wild events of "Congo Spider Fangs."
