The Borrowed Eye

A Novel of Leonardo da Vinci

Original Spanish title: El ojo prestado

Florence, 1473. Through a small piece of rock crystal, a young Leonardo begins to dream in fragments of a future he can’t make sense of — people flying, breathing underwater, talking to someone who isn’t there. Meanwhile, a messenger carrying one of his letters turns up dead by the Arno. A historical mystery with every clue in plain sight, an impossible love with Lisa Gherardini, and Leonardo’s art and inventions told through his craft — never through magic.
