Once A Frog Always A Frog — Mari Collier

Frogs of all sizes have overrun the farming community of Austin, Iowa. There are so many frogs, they cause accidents on the highway, people are arguing, fighting, and disappearing. Elvie Fedderman knows this is not a normal nature's cycle and begins a search to discover why her community is under siege. Follow her as she discovers frogs with intelligence and a cave that holds a deadly secret. Not everyone will walk away from that cave, others will hop.
