She came to Cape Point to study whales. She didn't expect the lighthouse keeper to see her.

Dr. Amara Okonkwo hasn't slept through the night in three years. Not since the dive that took Kwame — her research partner of eleven years, the man she loved and never told. She was on the vessel.

She didn't check his gear. So now the marine biologist keeps moving — from Lagos to a research fellowship at the edge of the world she barely remembers accepting.

When the position brings her to Cape Point, South Africa, she tells herself it's science. Track the whales. Log the data. Don't feel anything.

James MacAllister tends the Cape Point lighthouse. A solitary man with a Rhodesian Ridgeback named Darwin and no use for small talk, he maintains the light, walks the cliffs, and doesn't ask questions.

He doesn't ask Amara why she stands at the edge. He just invites her to dinner.

She came to study what survives in deep water. He's been surviving in deep water for years.

Between whale song and windswept cliffs, two people keeping vigil over things that cannot be saved might finally learn that grief can become something other than architecture — and that some things can only heal when they're witnessed.

Book Four in The Cape Town Series. A tender, closed-door later-in-life romance — quiet healing, slow-burn, and being truly seen.
