The Company books are about Dr. Zeus, a company of immortals who can send people back in time to rescue small children and things that are about to disappear in history. Mendoza, a young child who didn't know her own name, ends up with the Spanish Inquisition (yes, yes) and is harvested by Joseph, who has been a cyborg much longer. We skim through most of her cyborg training and botanist education and find that she's being sent to Queen Mary's England, to a country house with plants that can be saved for the future. Unfortunately, this part is amazingly boring. It turns into a bad Marythan romance, with religious overtones. I think the next book, Sky Coyote is better, but my favorite is Mendoza in Hollywood.
If you like mixing cyborgs and historical romances, this is for you.
