On Marin's island, sunrise doesn't come every 24 hours - it comes every 28 years. Now the sun is just a sliver of light on the horizon. The weather is turning cold and the shadows are growing long. Because sunset triggers the tide to roll out hundreds of miles, the islanders are frantically preparing to sail south, where they will wait out the long night.
Thousands of miles south of the island of Bliss, day and night last for 72 hours. Here is one of the natural wonders of this world: a whirlpool 30 miles wide and 100 miles around. This is the Drain. Anything sucked into its frothing, turbulent waters is never seen again. Wren has spent most of her life on Edgeland, a nearby island where people bring their dead to be blessed and prepared for the afterlife.
