Swordfish Island: Book Two of Swordfish Island Trilogy

Book one, The Swordfish Island Covenant, mentioned three kinds of spheres: many crystalfs, few sun jewels, and one ovivium. Found in beach sand, white crystalfs were first thought to be magic turtle eggs. They provide daily reminder that Swordfish Island was not simply a tropical paradise. Just picking one up caused a little burst of joy that relieved mental stress. In lovemaking a crystal shared, provided an emotional bridge between mates bringing them to simultaneous rapture. A colored crystal joined with a sun jewel began a process of rejuvenation that reset the person's biological clock to age twenty. Due to the limited numbers of sun jewels there was a conflict over who would rejuvenate. The islanders had many questions: Why weren't there more sun jewels? What was the purpose of the ovivium? What did these benefits cost?
