A HIGH-ALTITUDE BLIZZARD, BUBBLING RIVERS OF LAVA, AND BEACHES WITH RAGING SURF; one thing’s for sure: The Hawaiian Islands offer no shortage of adventure! Teaming up with fellow explorer, Alana Aukai, thrill-seeking twins Gannon and Wyatt begin an expedition to study rarely visited parts of this Pacific paradise. When an ancient map is found on a drowning archeologist, the explorers shift their attention to uncovering the map’s secrets. To their astonishment, they discover that it might lead to one of Hawaii’s most puzzling mysteries—the burial place of the islands’ most-revered ruler, King Kamehameha the Great! Adding danger to an already perilous journey, someone else is after the map—someone who seems willing to do just about anything to get it.
