Six extraordinary children are trying to lead normal lives in the Rocky Mountain countryside. They live in different homes with different families, but there is something powerful that connects them. Something that puts them in terrible danger. The only time they felt safe was when they were together in the waterfront cabin they call the Lake House. And the only people they've ever trusted are Frannie and Kit, the couple who rescued them from unimaginable evil once before. When that evil resurfaces, the kids reconnect with Frannie and Kit and set off on an astonishing adventure. They flee to the Lake House, but even that haven may no longer be safe.
