A thrilling new Wilbur Smith series for the next generation with high action and high stakes - starring teen protagonists Ralph and Robyn Ballantyne.

Ralph and Robyn live at Crocodile Lodge, their family ranch in South Africa, where they help with the animals, aid the conservation effort and learn the land. That is, until a mysterious predator starts terrorising the reserve.

On the trail for answers, the siblings discover the fearsome culprit: the largest crocodile they've ever seen, uncannily similar to the long-extinct Sarchosuchus Ralph recognises from his favourite game, Predasaur. And when a nearby village is ravaged by a deadly disease, seemingly stemming from a millennia-old animal, the stakes are higher than ever.

As Ralph and Robyn follow the clues, all roads lead them to Crocodile Lodge's infamous neighbour: millionaire tech giant and hunting enthusiast Josef Gerhard. Could it really be that Gerhard is bringing the beastly creatures of Predasaur to life - and at what cost?
