Less convincing than his own somewhat fictionized biographical yarn, Island of Desire -- and equally straight escape reading, with the treasure hunt appeal predominating and with less of the romantic angle. Again a story of adventure in the South Seas, as Allen Sustenance seeks a few years of rainbow's end at the atoll of Amaru. He has old friends there -- and new; he finds again, grown up this time, the girl he had remembered as a child; he finds too confirmation of a story of buried treasure and mad adventure -- and seeks that treasure, but finds another; and in the end learns the secret of old King Noah's buried pearls....Light weight -- rental library fare.
