This is the first novel in what has become one of the most popular series in contemporary Science Fiction, now back in print from Tor. In the twenty-fourth century, the Company preserves works of art and extinct forms of life (for profit of course). It recruits orphans from the past, renders them all but immortal, and trains them to serve the Company. One of these is Mendoza the botanist, who is sent to Elizabethan England to collect samples from the garden of Sir Walter Iden. Her quest is jeopardized by Nicholas Harpole, who stirs unfamiliar emotions within her about her future - with a man she will long outlive.
