Martin presents the book in three parts. The first part introduces the reader to the ecosystems of the island and the importance that animal traces play in documenting conditions and behaviors. Next, he discusses the history of the islands, including the Native American shell rings on Sapelo Island and the cobbled streets of Savannah. Finally, Martin explores how the Georgia coastline is changing. He asks how the traces of the past and present help us to better predict and deal with our uncertain future.
