If frogs come from eggs,
and eggs come from frogs,
where did the first frog come from?

This is the incredible story of how frogs came to be. To find out, we go all the way back to the very beginning. Before frogs, dinosaurs, planet Earth – before even the stars existed . . . back 13.7 billion years to the moment just before the universe began. And from there, through Isabel Thomas’s beautifully lyrical text and Daniel Egnéus’s breathtaking illustrations, we are transported through time to the evolution of the very first frogs.

The story of frog is an epic; an adventure in space and time. It’s a story still being told, in every garden, every pond and every corner of our extraordinary planet.
