Which of the words in the passage below best illustrates Ralph's feelings towards the island and the prospect of spending time on it?
Beyond the platform there was more enchantment. Some act of God - a typhoon perhaps, or the storm that had accompanied his own arrival - had banked sand inside the lagoon so that there was a long, deep pool in the beach with a high ledge of pink granite at the further end.
Ralph had been deceived before now by the specious appearance of depth in a beach pool and he approached this one preparing to be disappointed. But the island ran true to form and the incredible pool, which clearly was only invaded by the sea at high tide, was so deep at one end as to be dark green.
