Throughout this part of the book, in the beginning it takes place at Martha's front door, I think Martha's front door is big and wide because there was enough space for two people standing by it. Then another specific location in her house would be her room. In my opinion, I think that Martha's bedroom isn't very big, but is big enough for furniture.
This novel takes place around the summer because Martha is traveling to go see her Grandma. I imagine Martha at her grandmothers house on vacation, just and only thinking about Olive. Now all Martha can think about is Olive while Martha should really be spending her Summer vacation with her Family.
This book takes place in the summer, which means it is very hot. In my opinion, I think it would be very humid and people will never wear jackets, hoodies, jeans, or any clothes that make you perspire. The book would take place where the sun is shining during the day, but still warm at night.
