Publisher's summary
As the Earth's primeval rulers reclaim their birthright, UNIT must stand against them. Kate Stewart and Osgood venture into a Mediterranean stronghold to retrieve a means to fight back.

But a Silurian warrior is on their trail. Once she has the humans' scent, Commander Tryska will never give up the hunt.

Plot
A UNIT ship and its crew are killed by one of Krelix's bioengineered weapons. Trying to find the Silurians' device to control them, Osgood has identified a Silurian nest off the Greek coast as a research base. She and Kate head there and are spotted by Commander Tryska, who reports the threat that they pose to Grand Marshall Jastrok. When Kate and Osgood enter the underwater caves, Tryska attacks the soldiers outside and demands to know their mission.

Believing it to be for detecting Silurian life, Osgood uses a Silurian device which she soon realises is for attracting reptiles. Her second attempt at using a Silurian device proves successful when she uses another as a key for a passage leading deeper into the cave system. Inert Troodon wake up and toy with her and Kate, assessing how much of a threat they are, and Kate contacts Sam after they are trapped in a cave, but they find the way to a hibernation chamber and discover that the inhabitants are dead and rotting.

Tryska enters the nest, kills the Troodon and attacks Kate and Osgood, poisoning the former with her tongue and using a device that she has recovered to amplify the latter's race memory and make her made with fear. As Tryska chases Osgood, Sam finds Kate and gives her the broad-range antivenom as a temporary measure before going to save Osgood.
