Eve has no idea she’s the oldest soul on earth, with a pre-wired connection to every other soul on the planet. The boy she’s mysteriously drawn to, named Roman, has been her soul mate, her love of nearly three hundred lifetimes—until he tells her.

But what Roman doesn’t mention is that the new genetic test called Animus will soon expose what she is to the whole world, and that he’s being tasked with the impossible; steering her into the open arms of another, a boy named Jude. She’ll learn that Jude’s the only brand new soul on earth; the one who’s come to change the world, and that the future of humanity rests in their intertwined destiny.

Who knew that mapping the genome would lead to carbon dating the soul? With scientists on the brink of decoding our DNA to determine the number of lifetimes a soul has lived, Eve meets a spellbinding boy named Jude, and finds herself fatefully drawn to both him and Roman, her apparent love of lifetimes. But how will she choose between her soul mate and her fate? With no idea that her choice will alter the course of history, paving the way for a world war of old souls versus new.

When you can’t trust yourself, who can you believe?

Everything about Anna’s life is a secret. Her father works for the Branch at the helm of its latest project: monitoring and administering treatments to the four genetically altered boys in the lab below their farmhouse. There’s Nick, Cas, Trev . . . and Sam, who has stolen Anna’s heart.

When the Branch decides it’s time to take the boys, Sam stages an escape, killing the agents sent to retrieve them. Anna is torn between following Sam or staying behind in the safety of her everyday life. But her father pushes her to flee, making Sam promise to keep her away from the Branch, at all costs. There’s just one problem. Sam and the boys don’t remember anything before living in the lab—not even their true identities.

Now on the run, Anna soon discovers that she and Sam are connected in more ways than either of them expected. And if they’re both going to survive, they must piece together the clues of their past before the Branch catches up to them and steals it all away.

From New York Times bestselling author Sam Kean comes incredible stories of science, history, language, and music, as told by our own DNA.

In The Disappearing Spoon, bestselling author Sam Kean unlocked the mysteries of the periodic table. In The Violinist's Thumb, he explores the wonders of the magical building block of life: DNA.

There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists.

Kean's vibrant storytelling once again makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.
