**This endlessly fun and hugely entertaining romp through Europe had me laughing out loud and reaching for my passport.” —Jennifer E. Smith, author of Windfall** **A POPSUGAR Best Young Adult Novel of 2017!** Nineteen-year-old Sydney has the perfect summer mapped out. She’s spending the next four and a half weeks travelling through Europe with her childhood best friend Leela. Their plans include Eiffel Tower selfies, eating *cocco* gelato, and making out with *très* 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 *très* hot friend, monitoring her mother’s spiraling mental health via texts, or feeling like the rope in a friendship tug of war. In this hilarious and unforgettable adventure, *New York Times* bestselling author Sarah Mlynowski tells the story of a girl learning to navigate secret romances, thorny relationships, and the London Tube. As Sydney zigzags through Amsterdam, Switzerland, Italy, and France, she must learn when to hold on, when to keep moving, and when to jump into the Riviera…wearing only her polka dot underpants.
