Fiordland has been waiting for them....and you. Memories of the past call out to those brave enough to dream of an incredible land. Teen twins Seth and Zoe are flung through time once again, returning to the thrilling Fiordland of the past after their secret wish comes true. The siblings find themselves on a private tour of the wonder of Doubtful Sound, following the lead of legendary guide Leslie Murrell through the wild and remote wilderness. The winding trails of the Wilmot Pass and the dark waters of Deep Cove beckon the young teens to chase their dreams, taking Zoe back to a time where the mighty ocean liner Wanganella is once again moored at Deep Cove, and the power of water becomes industry. Seth's quest for safety will force him to make a haunting choice, leading him south to the windswept Puysegur Lighthouse, and plunging him into the history of the sea. Zoe and Seth must steady themselves in the face of great change. For time travellers beware: Fiordland's promise of adventure is a double-edged sword. In the pursuit of their dreams, these young teens must struggle for their survival deep in the heart of New Zealand's wild south. At the edge of the world awaits the adventure of a lifetime - but will the lessons of the past be enough to save them? Only time will tell.
