From the day Cobb and Mary meet kayaking on Maine's Allagash River and fall deeply in love, the two approach life with the same sense of adventure they use to conquer the river's treacherous rapids. But rivers do not let go so easily...and neither does their love. So when Mary's life takes the cruelest turn, she vows to face those rough waters on her own terms and asks Cobb to promise, when the time comes, to help her return to their beloved river for one final journey.

Set against the rugged wilderness of Maine, the exotic islands of Indonesia, the sweeping panoramas of Yellowstone National Park, and the tranquil villages of rural New England, Eternal on the Wateris at once heartbreaking and uplifting -- a timeless, beautifully rendered story of true love's power.
