The Diamond of Darkhold by Jeanne DuPrau
Rating: 4 stars (out of 5)
Genre: science fiction, childrens
Review: I'm not sure why DuPrau chose to gradually lower the reading level of this series, but this book reads much more like a book for children than the first three in the series, even though the characters and subject matter remain on a young adult level.
Be that as it may, this is still quite a good book. In the third book, the people of Ember and the people of Sparks are just barely managing to live together harmoniously, but conditions have not improved over the hard winter. Food is scarce and tempers are running short. When Lina and Doon discover a book that describes something left behind for the people of Ember, they decide to go back to their city and try to find this mysterious item, as well as see what supplies may have been left behind when the people left.
What they discover allows DuPrau to end her series on a very hopeful note. She does not disguise the fact that life continues to be hard, but she makes it clear that by working together, the people of Ember and Sparks are able to come together and make a bright new future. As cheesy as that sounds, she writes it so well that you can't help but smile and feel hopeful yourself.
