Ezzy Skylar, her brother Luke, and their father embark on a trip to number two on her deceased mother’s wonder list—Greenland’s Kangia Icefjord. While worrying that she didn’t inherit her mother’s gene for adventure, Ezzy and her family become embroiled in a dangerous plot. A flight across an obstacle course of icebergs, some hungry humpback whales, and a wild kayak ride atop a river inside a glacier will test Ezzy’s bravery and lead to an astonishing discovery.
