Heartache and the minefields of dating are explored in Laura Zigman's humorous new novel ANIMAL HUSBANDRY. The premise of the book comes from a true scientific theory--the Coolidge Effect. This theory is based on the premise that bulls will only mate with a cow once--then they're off to seek a new cow. Zigman stumbled upon the theory as she flipped through science journals while nursing her broken heart. She jokes, if you bring things back to the animal kingdom--dating behavior makes sense. Zigman says her main character--Jane Goodall--is autobiographical.
