Henrietta O'Dwyer Collins, better known as "Henrie O", has experienced much sadness and loss in her life - yet nothing more tragic than the sudden death six years ago of her husband, Richard, on Kauai. Then, on a brisk March morning, a package arrives by courier that shatters her fragile peace of mind - a chilling message that claims Richard's fatal fall from a towering island cliff was no accident. It was murder. It is news that enrages the normally self-contained Henrie O, and creates a summons she cannot ignore. She follows cryptic clues and her infallible instincts to a secret-shrouded tropic Eden - a lush and verdant Pacific paradise where giant palm fronds hide evil deeds from inquisitive eyes and the soft, salt-scented ocean breeze whispers of treachery and death.
