As tour escort Emily Miceli leads her globetrotting band of Iowa seniors into the wilds of Alaska, she discovers that, in the land of the midnight sun, whales aren't the only killers on the prowl. When a tour member turns up dead on a mountainous hiking trail, Emily blames herself for the mishap--until she learns that something far hairier might be to blame. One of the seniors snaps a photo of what looks to be Bigfoot, raising many questions about what happened to the victim. But the illusive sasquatch is just a legend, isn't it? Between whale-watching in the glacial waters near Seward and ziplining in the primal forests of Denali, Emily finds herself locked in a game of cat and mouse with a killer who's too clever to be mere myth.
