Lincoln Child (born 1957) is an American author of multiple techno-thriller and horror novels. Though he is most well known for his collaborations with Douglas Preston (including the Agent Pendergast series and the Gideon Crew series, among others), he has also written five solo novels, including the Jeremy Logan series. Many of the collaborative novels have become bestsellers, and their first novel together, Relic, was adapted into a feature film. Child and Preston's books are notable for their thorough research.
