Nightfall By Isaac Asimov and Robert Silverberg

We meet at picnic area 3 at Kaka'ako Waterfront Park.
Nightfall by Isaac Asimov and Robert Silverberg was originally a short story first published in 1941 in a SF magazine, but was later expanded into a novel. Imagine a world with 6 suns where it is never dark except once every thousand or so years when the alignment of planets and suns bring darkness to the world causing civilizations to falter.
