The game of Go is mentioned on page 302: ""Go was a game of strategy. It suited the devious mind."
from the back of the book:
Forensic anthropologist Aisha Costard has been summoned to Mars to examine skeletal remains recently discovered beneath a building erected by the Disty aliens. The bones belong to a human woman who vanished thirty years ago with her children. She is believed to have been one of the Disappeared, outlaws wanted for crimes against alien civilizations.
To investigate the mystery of the skeleton, Aisha turns to Retrieval Artist Miles Flint. Following the trail back three decades and seeking the whereabouts of the victim's missing children, Miles discovers a deadly secret that could threaten the stability of the entire solar system...
SFRevu closes their review with this: "Buried Deep is an exciting, intricately plotted, fast-paced novel. You'll find it difficult to put down. Highly recommended for both fans of the Retrieval Artist series and newcomers."
