But there are deeper rhythms, too. The tides flood the estuaries and marshes twice a day. The birds and fish keep to migratory patterns established thousands of years ago. And surrounding it all is the ocean, a tangible presence, a living god, sometimes benign, sometimes angry, giving all who gaze upon it a sense of limitless possibility and insignificance, too.

The Pilgrims and their descendants set out to tame the world they found on Cape Cod. They saw it as part of God’s plan. They harvested the whales on the beaches and hunted the whales in the bay. They stripped the trees for lumber and firewood and burned the forests to clear their fields. They struggled, sometimes violently, with the Wampanoag Indians, whose name means “children of the dawn” and whose gods were as real to them as the Christian God was to the Pilgrims.

Generations of shipwrights, seafarers, and fisherman followed. They built the neat villages and towns of Cape Cod. But they seldom built houses looking out to sea because, as one old Cape Codder told me, “The sea was a place of work and death.”

Then Henry David Thoreau came for a visit just before the Civil War. He looked out to sea and into the future. And he wrote, “The time must come when this coast will be a place of resort…” He was right. Before long, the wealthy were building mansions at the ocean’s edge. And then vacationers arrived for those two-week summer rentals that are as much a part of the Cape’s seasonal rhythm as the migration of the whales.

I’ve been in love with the Cape since boyhood, and once I began to write novels, I knew that someday I would tell the story of the place and its people and their unique relationship to nature.

I decided that I would tell it from the beginning… or from before the beginning. That’s why the book opens as it does, with a whale stranding observed by… well, read the book to find out. And I knew I could not tell it without the Pilgrims, the first of so many who came to the Cape to find freedom or fulfillment. And I would close the narrative circle by bringing the story all the way to the present, to a family of Pilgrim descendants struggling over their ancient birthright.

A hundred people sailed on the Mayflower. They called themselves Saints and Strangers. Some were religious separatists. Others had joined the voyage just for profit. Fifty survived the first winter, and while many of them were filled with piety, all of them were tough, resilient, and resourceful. The proof is that today, more than ten percent of the American population can trace their ancestry back to those fifty.

They were like us in some ways… but very different, too.

The senior historian at Plimoth Plantation, the Pilgrims’ living history museum, put it best. He said that the Pilgrims had all the big things figured out. They understood their relationship to God and eternity. It was only the little things that troubled them, the daily problems of shelter, fuel, and food. We, on the other hand, have most of the little things settled, but it’s our place in the cosmos that leaves us wondering.

If this novel has a theme, a big idea, it’s in that observation.

But don’t bother yourself too much about the big ideas. I’m a storyteller. My job is to keep you up past your bedtime. And it’s the story that has kept readers turning these pages for two decades. Let the thousand-year plot wash over you while the characters in the smaller plots—Saints and Strangers, praying Indians and Wampanoag warriors, rebels and royalists, slave runners, rumrunners, show runners, whaling men, fishermen, oystermen, real estate agents, developers, and conservationists—swirl around you and sweep you through time.

They’re all after a secret.
