From an advance review:

Sciolino’s keen eye and vivid prose bring the river to life as she discovers its origins on a remote plateau of Burgundy, where a pagan goddess healed pilgrims at an ancient temple. She follows the Seine to Le Havre, where it meets the sea.  Braiding memoir, travelogue, and history through the Seine’s winding route, Sciolino offers a love letter to Paris and the river at its heart and invites readers to explore its magic.

In the spring of 1978, as a young journalist in Paris, Elaine Sciolino was seduced by a river. In The Seine, she tells the story of that river through its rich history and lively characters—a bargewoman, a riverbank bookseller, a houseboat dweller, a famous cameraman known for capturing the river’s light. She patrols with river police, rows with a restorer of antique boats, discovers a champagne vineyard, and even dares to swim in the Seine.
