There is a legacy that stands at the center of the island, a gift of heart and hard work given by one man to Vashon’s community of people and plants, birds and animals. That man was Bill Fisher, and his gift was the 90 acres that make up the natural ecosystem of Fisher Pond.

In a new book, “On Fisher Pond: Memories of Bill Fisher and His Gift to Vashon Island,” Laurie Bevin Stewart created a poprtrait of Fisher — his philosophy, ethics and actions — by weaving islanders’ remembrances with her own poignant experiences to create a poetic essay and tribute to Fisher’s stewardship and remarkable generosity. The author will read from her new book at 6 p.m. Wednesday at Vashon Bookshop.
