Waking Gods is a terrific follow up to Sleeping Giants!  Neuvel kept the same basic format: interview transcripts and journal entries to narrate the story.  You might think this would inhibit character development, but it really doesn't.  The personalities of the main characters shines through, as well as a rich story about love, fear, and the end of the world.  Taking place years after the original novel, you jump right back into the action.  There are quite a few heavy themes explored here, but the story kept me  interested to the very end.  Loved it!
