The Diamond of Darkhold by Jeanne DuPrau

2.0

2.5 stars . . . it felt like a way to eke more out of the story, although the "diamond" and its purpose were just strong enough for me to feel like the story was worth it, however, the addition of something at the end of the book, felt like a not very well meshed way of tying it to the prophet of yonwood book.
