Cat's Eye Shells by Wendy Joubert This is for a pdf download of my correspondences for cat's eye shells, not for actual cat's eye shells. Wendy Joubert is author of Sea Witch. This book was the first of its kind being solely on sea magic. Copyrighted in 2006, first published in 2008, and updated in 2022, it's been a favorite amongst sea witches and witches alike.
