The Gardener is by S.A. Bodeen. When Mason goes to visit his mom at the nursing home where she works he never expects to wake a beautiful young girl from a coma and run away with her. But here he is on the run with a girl who doesn't need food or water and who is being hunted by the Gardener, a genius who runs a greenhouse that grows people instead of plants. A very interesting trip into science fiction, definitely worth a read.
