The Bone Labyrinth: A Sigma Force Novel

In bestseller Rollins’s thrilling 11th Sigma Force novel (after 2014’s The 6th Extinction), Painter Crowe, the director of Sigma Force, calls on his number-one operative, Cmdr. Gray Pierce, to investigate an attack on a group of scientists exploring a massive cave in the mountains of Croatia. One of the scientists, geneticist Lena Crandall, along with her twin sister, Maria, is attempting to find the origin of human intelligence. Maria’s research centers on her work with a three-year-old male lowland gorilla, Baako, who’s a hybrid of gorilla and Neanderthal genes. When Maria and Baako are kidnapped, the story kicks into high gear. Several parallel plots involve adventure fiction elements such as ancient petroglyphs, moldy historical journals, mysterious keys, and several astonishing underground cities. Rollins knows just how to balance the science and history with the ongoing action. [em]10-city author tour.
