"Nineteen-year-old Sydney has the perfect summer mapped out. She's spending the next four and a half weeks traveling through Europe with her childhood best friend Leela. Their plans include Eiffel Tower selfies, eating cocco gelato, and making out with hot strangers. Her plans do not include Leela's cheating ex-boyfriend showing up on the flight to London, falling for the cheating ex-boyfriend's hot friend, monitoring her mother's spiraling mental health via texts, or feeling like the rope in a friendship tug of war."--Jacket.
