In Annie Hartnett's new novel "Unlikely Animals" (Ballentine Books), natural-born healer Emma Starling once had big plans for her life, but she’s lost her way. A medical school dropout, she’s come back to small-town Everton, New Hampshire, to care for her father, who is dying from a mysterious brain disease. Clive Starling has been hallucinating small animals, as well as having visions of the ghost of a long-dead naturalist, Ernest Harold Baynes, once known for letting wild animals live in his house. This ghost has been giving Clive some ideas on how to spend his final days.
