New York City: A thirteen-year-old boy named Tyler lies in a hospital, his brain damaged in a tragic accident. By his bedside, his father stands helplessly, as two very different scientists take charge of the boy's fate. One is a neurosurgeon, whose unorthodox experiments use computers to control a patient's physical responses during surgery. The other is a researcher with experiments of his own, ones so secret he can reveal them to no one: his attempts to find the spark of human consciousness...and capture it forever. Together, they will produce a result beyond anything they could have conceived, sending Tyler far beyond the frontiers of medical science into an astonishing netherworld of man and machine - a place no living person has gone before and from which one desperate person will try to bring him back....

On an island off Georgia, clones are raised for body parts. After his girlfriend is eviscerated, clone Skyler flees to the mainland where he sees a book with the picture of a journalist who looks exactly like him. The two join forces to destroy the cloners. By the author of Neanderthal

When a Harvard paleontologist disappears in the mountains of northern Asia, Matt Mattison and Susan Arnot--former lovers who are now academic rivals--set out to find their mentor and a species of humans who have existed for over forty thousand years.

From the author of the bestselling Neanderthal comes this novel of gripping suspense and scientific conquest–a page-turning historical mystery that brilliantly explores the intrigue behind Darwin and his theory of evolution.It’s 1831, and aboard HMS Beagle the young Charles Darwin sets off down the English Channel for South America. More than 150 years later, two ambitious scholars pursuing their obsession with Darwin (and with each other) come across the diaries and letters of Darwin’s daughter. What they discover is a maze of violent rivalries, petty deceptions, and jealously guarded secrets, and the extraordinary story of an expedition embarked upon by two men. Only one returned–and changed history forever.
