On the colony world of Newhaven, biologist Travis Denholme has refined the drug by which the planet's alien species achieve telepathic contact. He has the means of bringing telepathy to the human race, and faces the dilemma of whether to make his discovery public knowledge - and risk changing everything. But before he and psychiatrist Kat Manning can decide on a way forward, an assassin attempts to kill them. As they flee for their lives, they must find out not only why they are being targeted by a ruthless killer, but why someone is trying to eradicate the planet's largest lifeform, the geosaurs.
