Sixteen-year-old Lucy Kane hates the uber-popular PSL. She finds it overrated -- especially when you consider the fact that there isn't even pumpkin in it! -- which is bad because she works at Cup o' Jo, the local coffee shop her mom owns. Business at Cup o' Jo hasn't been great in the off-season, but that's okay because it always picks up during the fall... Until Java Junction, a multinational coffee chain, opens across the street and makes things harder for the small shop. And to make matters worse, it turns out Jack Harper, the new kid in school and Lucy's secret crush, is the son of the owner.
