Poseidon Adventure by Paul Gallico

A luxury ocean liner is overturned by a disastrous wave on New Year’s Eve, leaving a small, disparate group of passengers trapped in the inverted hull; led by a determined clergyman and joined by a tough cop, a dancer, an ingénue and others, they brave flooded passageways, collapsing decks and their own doubts as they mount a perilous, improvised climb toward the distant surface, testing courage, leadership and faith in a desperate struggle to survive.
