When Frank and Joe Hardy set out for a winter holiday on the desolate, ice-bound Cabin Island, they expect nothing more than peaceful days of skating and cozy fires
. But from the moment they arrive, something feels wrong. A strange man is lurking in the woods, a bitter rival seems to know more than he lets on, and the island's long-abandoned cabin holds whispers of a mystery long buried beneath the snow.
As a powerful blizzard bears down, the Hardy boys find themselves racing against time-battling the elements, cracking hidden codes, and uncovering a secret that someone will do anything to keep hidden. The deeper they dig, the more dangerous the island becomes.
Snowbound and cut off from help, can Frank and Joe unravel the island's chilling mystery before it's too late?
