Bria Muller is stuck on her aunt and uncle's dairy farm for the summer, and she is not happy about it. Milking cows alongside her cousins Wren and Luke? No thanks. The one thing she's good at is mixing up milkshakes in the creamery. Instead of their usual vanilla, she starts crafting towering, over-the-top shakes like the ones she loved sipping back home in Chicago. Wren, and most of the customers, aren't impressed. Everyone seems to think Bria is just a snobby city girl. There is one person who appreciates the sweet, cold treats: Gabe, her cousins' cute friend who helps out on the farm. But with the family business in danger of being sold, can Bria's shakes make a difference . . . and will she ever fit into country life?
