4.5 stars. Super cute! I loved it. There were obviously some more cliche moments (with all the lying of course), but the rest of the book was definitely enough for me to forgive that. Swoony romance, adorable main character, and MAJOR wanderlust feels. I need to go to Europe. 
 ------------ 
 Full thoughts: What an adorable, swoon-filled read this was! I have loved international-travel-oriented books in the past because it usually gives me insane feelings of wanderlust. (Meant to Be and Just One Day/Year to name a few highly recommended reads!) I've actually never been out of the country and this book definitely got me thinking about it. Amsterdam sounds particularly beautiful and luckily that's at the top of Chris's travel list too! Anyways, back to the book... 
 I wasn't sure what to expect but I really wanted a nice fluffy contemporary involving cool places in Europe. That's exactly what I got! There were a few main elements of the story that led to some predictability (basically the big ol' lie to everyone), but the cute/swoon factor completely overpowered any qualms I had with cliches. 
 The story centers around Aubree, who is the reason her sister (Elizabeth) got arrested and can't take a group of senior citizens on a European tour group. She fills in for her, lies to her parents about where she is for the summer, and pretends to be her sister all around Europe. She also meets a VERY CUTE BOY who happens to be the tour company's owner's son. You can assume from this description what will end up happening, but it's the journey of the whole story that makes it great. 
 I loved reading about the different countries and getting to know the 6 seniors onboard. They were all fantastic and had such distinct personalities. I wish there was even more of them, if that were possible. Major feels from every single character in this book! 
 The biggest thing I loved - aside from the romance - was the natural character development for Aubree. She starts out as a complete mess and loses some important stuff on the airplane. Her and her sister have a weird relationship that only gets more complicated with this summer trip. All of this changes and improves so nicely throughout the story; you almost don't even see it happening. I was rooting for her every step of the way. Loved it. 
 Okay, so the boy. Sam was so great. I shipped them before they even met, when they had adorable phone conversations. I was really hoping there wouldn't be a lot of drama and angst surrounding Aubree-pretending-to-be-Elizabeth because I just neeeeded them to be happy. I won't spoil anything, but this book delivered on the swoons. 
 Overall, SO glad to have read this book. It was the perfect blend of travel, love, friendship, and family feels.
