In The Bone Labyrinth Rollins starts with the premise that tens of thousands of years ago, some Neanderthals mated with homo sapiens and produced a highly-intelligent offspring--the ancestors of modern man. He then takes us to Rome, in 1969, and reveals the existence of a map that could reveal the location of Adam and Eve's bones. Then it's on to current day and a research facility in Atlanta, where Maria Crandall, a geneticist, is doing remarkable work with a hybrid gorilla named Baako. Baako is extremely intelligent and can speak fluent sign language.
The action begins when Maria and Baako are kidnapped by Chinese forces and taken back to a research facility in Beijing. The Chinese--in true Chinese fashion--are close to creating a race of superhumans, but need to unlock the mysteries behind why human intelligence increased so dramatically all those thousands of years ago.
Part of me feels like I should be embarrassed to admit to reading books like these. But I'm not. I'm owning my guilty pleasure. I like this series. There's nothing wrong with checking your brain at the door and suspending disbelief occasionally while you read a story that's just fun and exiting. The Bone Labyrinth is a worthy addition to the series. I enjoyed it and am looking forward to picking up The Seventh Plague next month.
