The Jewel and the Key by Louise Spiegler
My rating: 2 of 5 stars
I was disappointed that the initial tension (would Addie get a role in the upcoming high school production, or would the "drama divas" win again?) was completely ignored by the time we were 1/4 in to the book. The time travel to WWI-era Seattle and the parallels between the people's feelings about the war then and the contemporary wars was interesting, particularly as many history classes don't cover that era and the IWW/Wobblies in as much depth as they used to. However, Addie's traveling between the eras, her attempts to save the Jewel, and her relationships with people in both times were retreads of other time-travel adventures I've read.
