Publisher's Synopsis
Ecology and pollution are simply not in 12-year-old Jan Calvin's vocabulary. But when her family moves to Pinemarsh, Louisiana in the summer of 1963, she uncovers a mystery that can only be solved with science: Something strange is killing the swamp, something that is wilting the cattails and killing the fish and turtles. Jan and her new friends snoop around, unearthing clues to a most surprising--and disturbing--secret. But can they save the swamp?
