Dr. Peter Chesterfield is the top neurosurgeon at the Royal London Hospital. He’s also a workaholic, and after a blow-up with a colleague, his boss orders him to attend a medical symposium at the luxurious Elysium Grand on the island of Maui. During a midnight walk on the beach, Peter pulls a woman with a skull fracture from the water. Despite all his skill, she dies in his arms, leaving him with only one clue to what happened to her: the word honu.
