For Darkness Shows the Stars
If Elliot were to go on vacation and she had to bring three things she would probably bring these three things, the compass that her grandfather left her in his will, Ro and her flower seeds, and some essential clothing. I know that she would defiantly bring the compass and Ro because towards the end of the book when Kai asked her to go with him on his adventure. In chapter 43 Elliot says "Be fair to the workers. Water the crops. We'll be back in time for the harvest," so this is kind of like her own little vacation. The only thing not actually mentioned in the story is the extra clothing but that's just something extra to have.
