Have you ever wondered what it would be like if you were an ado­lecent boy or girl and you were given the incredible gift of invisibility? And suppose you could heal animals and people but you couldn't tell anyone? In this second book of The Promise series, two ordinary brothers, Peter and David Wilson, from a rural town in New England, and eventually a beautiful young girl from Brazil, are given these gifts and more. But special gifts often require extraordinary sacrifice. No one-friends, school mates, even Mom and Dad-can know of these remarkable abilities. For if they do, their gifts will vanish in an instant. Is the cost of this secrecy too high? Can they juggle everyday life with their newfound talents? Travel with these special youngsters and learn from their mysterious mentors in a fantastic adventure as they use their amazing powers to help save the beleaguered earth.
