This new discussion series focuses on mysteries.  The selection for this month is Winter Study by Nevada Barr.  Readers who have followed intrepid forest ranger Anna Pigeon fighting fires, crawling through caves, investigating crimes at national monuments, and tracking bears in service of the National Park system will find her back almost where she began, at Isle Royale National Park.  The series is facilitated by Judy Dearlove, who has called Durham home for over three decades.  A passionate reader, she has also taught literature at several local colleges, including Duke, Meredith, and Elon.  Currently, she is engaged in the mysterious process of writing a novel.
