Showing Mendoza in Hollywood by Kage Baker

This is the third novel in what has become one of the most popular series in contemporary SF, now back in print from Tor. In the 24th 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, Dr. Zeus. One of these is Mendoza the botanist. The death of her lover has been followed by centuries of heartbreak. She spends a period of time in early twentieth century Hollywood in the days of D.W. Griffith, and then Mendoza is in the midst of the Civil War, and runs into a man that looks disturbingly similar to her lost love. She is about to find love again, and be in more trouble than she could ever have imagined.
