There’s someone alive out there. After three perilous years on a planet full of dinosaurs, Caleb and his colony have finally found safety. The ‘saurs are kept at bay, the crops are growing, and for the first time in centuries, humanity might have a future. But a single voice changes everything. The colony receives a call for help from a girl they haven’t seen since the crash and realizes that they are not the only humans still alive. On an empty beach at the far edge of the continent, the survivors of Transport Seventeen have huddled in terror for three long years. Now they’re out of food and out of time. Caleb and his friends must leave the safety of their home to rescue the survivors. As they travel into the unexplored depths of the jungle, they face danger from above, from the darkness, and from the water. And soon they discover there are new ‘saurs out there, ones that would scare even a T-rex.
