Synopsis: "Several college friends start planning a two week kayak trip down an Alaskan river during late summer 1992. Soon there are five young people headed to Alaska for a river expedition. As the trip unfolds and the group gets farther into the wilderness a strange whispering sound attracts their attention. The wonderful vacation begins to take a turn for the worse when they follow the sounds and find something long lost and quite unexpected." — quoted from this book's product page on Amazon as of 2018-06-22.
