Title: The Diamond of Darkhold
Author: Jeanne DuPrau
Year Published: 2008
Synopsis: It’s been several months since Lina and Doon escaped the dying city of Ember and, along with the rest of their people, joined the town of Sparks. Now, struggling through the harsh winter aboveground, they find an unusual book. Torn up and missing most of its pages, it alludes to a mysterious device from before the Disaster, which they believe is still in Ember. Together, Lina and Doon must go back underground to retrieve what was lost and bring light to a dark world. In the fourth Book of Ember, bestselling author Jeanne DuPrau juxtaposes yet another action-packed adventure with powerful themes about hope, learning, and the search for truth.
Why?: I read the rest of the series, I might as well read the last book.
Expectations: After The Prophet of Yonwood, my expectations are a little higher for this book than they otherwise would have been. Except Lina and Doon are in it, so I'm sure they'll ruin it somehow.
Judging a book by its cover: It looks like the book will deal with a big blue diamond. And it's sparkly, so maybe it has to do with the sun too. Oh and desert everywhere.
