I'm enjoying this so far. Anything about elephants is good to me. From the back cover:

Jacob, a veterinary student who almost earned his degree, is put in charge of caring for the circus menagerie. It is there that he meets Marlena, the beautiful young star of the equestrian act, who is married to August, the charismatic but twisted animal trainer. He also meets Rosie, an elephant who seems untrainable until he discovers a way to reach her.
