Deep in a tiny pond lives the most curious ?and funniest? scientist who ever kept a notebook made of tree bark.

My friend Frog didn't always know he was a frog. As a tadpole, swimming among fish, he was convinced he was one too. But a curiosity that wouldn't let him rest led him to ask the question that would change his life forever: why does this pond work so well?

So begins the story of a tadpole who becomes the first Scientific Guardian of his home, builds a team of squads with a tiger salamander, ancient dragonflies, and patient snails (and even a groundhog who never says a word!), and discovers, through laughter and real scientific breakthroughs, the secrets that hold nature's perfect balance together: the water cycle, photosynthesis, the food chain, and the astonishing invisible world of phytoplankton.

But when a silent problem begins to overflow his pond ?and threatens a faraway bay full of exhausted mussels? my friend Frog will learn that understanding science isn't enough: you have to act to protect what you love.

A scientific adventure, tender and full of humor, for readers ages 9 to 12 who love animals, asking questions, and discovering how the world around them really works.

Perfect for curious kids, future scientists, nature lovers, and families looking for a story that entertains and teaches at the same time ? no lectures, just real science and a protagonist impossible not to love.
