Book Release Celebration for Melissa Hart (Eugene).  Melissa’s new book, “Avenging the Owl,” a highly reviewed middle-grade novel, “deals with the difficult issues of suicide and depression, but more than anything it deals with the powerlessness of being a kid.  It won’t be easy, but the wild beauty of Oregon, its cold, empty beaches and captivating wildlife, may be just what Solo and his family need to help them start over.”  Melissa’s events are always a hoot.  This time she’s got 10 nature and writing non-profits hosting tables, and winners from her regional middle-school essay contest will read their work.  Light refreshments.  Signing to follow.
