"Tallulah is ready to start her work as the Great Lakes’ first official mermaid! After taking the pledge to protect and care for the lakes, she’s off--caring for the various creatures that call the Great Lakes home, keeping the water and shores safe and clean, helping the boats navigate the waterways, and more! It’s a big job. And when a raft carrying a pair of children gets swept from the beach into rough waters, she swims into action."--
