Best-selling Cambridge-based author Neil Gaiman , of “American Gods,” “Coraline,” and “The Ocean at the End of the Lane,” has accepted a position at Bard College, according to the New York school. Starting next spring, he’ll be a member of the Theater and Performance faculty, and will teach an advanced writing workshop about fantasy fiction. Gaiman is married to another local — musician and social media queen Amanda Palmer . We assume that the couple will remain Massachusetts residents. Based on what we’ve seen, Gaiman doesn’t like to stray too far from Porter Square Books.
