A Dark Christmas is set nine years after the events in The Siamese Connection. Martin's daughter Nina is now nine and his eighteen-year-old adopted Cambodian son Hon is a musical prodigy. The boy's amazing talent was instantly recognizable the first time he sat down on a piano bench. He is rehearsing for his first album to be followed by a world tour.

As Christmas rapidly approaches, things become tense in the LaRue household and in the studio as Hon's mysterious French girlfriend Juliette arrives - commanding more and more of Hon's precious time.

Tragedy strikes on Christmas Eve, bringing Martin and Ramonne together once again to face, perhaps, their greatest and most powerful modern enemy.

The tale shifts back and forth between 1947 and present day. Ramonne and Jim Thompson end up doing battle with The Black Dragons when Ramonne reveals he has the Oracle.

Back in the present - Ramonne knows the Japanese have contacted Martin. He reveals what he knows about the Black Dragons and The Oracle.

Areeya is admitted to the hospital for the baby's birth. But she is kidnapped from the hospital and Ramonne and Martin trace her to the Hernando Cemetery where Muraki is prepared to make her a human sacrifice in his mad quest for immortality.
