When Adriana, a brilliant young archaeologist, accepts a position at the Museum of Archaeology in her hometown of Santander, Spain, she never imagines that her new boss has lived through the history she can only study.

Iago, the charismatic technical director of the museum, is more than ten thousand years old but appears to be only thirty-five. Iago and his family are longevos—people who never seem to age after reaching adulthood.

The ancient family is divided: Iago’s brother and sister seek the source of their longevity in hopes of creating more like themselves, while Iago and his father fear the repercussions of the true Fountain of Youth.

A dangerous game of power and knowledge that has played out over eons becomes even more complicated when Adriana attracts both brothers’ attention—and learns their secret.

Filled with science, history, and passion, The Immortal Collection transports the reader through time and space, from the days of cavemen, through the Roaring Twenties, to the charming plazas of contemporary Spain. Ancient history meets cutting-edge research in this modern love story and sweeping historical saga.

Less than 50,000 years ago, humans had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic change, described by scientists as 'the greatest riddle in human history', all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers.

In Supernatural, Hancock sets out to investigate this mysterious before-and-after moment and to discover the truth about the influences that gave birth to the modern mind. His quest takes him on a detective journey from the beautiful painted caves of prehistoric France, Spain, and Italy to rock shelters in the mountains of South Africa, where he finds extraordinary Stone Age art.

He uncovers clues that lead him to the Amazon rainforest to drink the hallucinogen Ayahuasca with shamans, whose paintings contain images of 'super-natural beings' identical to the animal-human hybrids depicted in prehistoric caves. Hallucinogens such as mescaline also produce visionary encounters with exactly the same beings.

Scientists at the cutting edge of consciousness research have begun to consider the possibility that such hallucinations may be real perceptions of other dimensions. Could the supernaturals first depicted in the painted caves be the ancient teachers of humankind? Could it be that human evolution isn't just the meaningless process Darwin identified, but something more purposive and intelligent that we've barely begun to understand?
