Across the Universe Book 2: Impossibly Real

You don't have to, but I suggest reading Pieces of Destiny first. Aria, Anakin, Obi-Wan, and Padme left Earth, but they're not where they expected to be. Instead of going back to just before the Clone Wars, they have ended up in the middle of the Original Trilogy, and are already leaving a lasting impact. Will they be able to get everyone out alive? Or make things so much worse?
