Horseshoe crab advocates turned out in force at Water Street Bookstore in Exeter, N.H., for Caroline Sutton and her new book, Eyes in the Soles of My Feet: From Horseshoe Crabs to Sycamores, Exploring Hidden Connections to the Natural World (Schaffner Press). The event was co-sponsored by Great Bay Stewards, a nonprofit whose mission is the long-term protection and conservation of the nearby Great Bay estuarine system by supporting education, land protection, research and stewardship. The Great Bay is home to endangered horseshoe crabs that are monitored by scientists and volunteers. Water Street donated a portion of the evening's proceeds to Great Bay Stewards.
