I Ate This Up!

 The Prince & The Apocalypse  by Kara McDowell 

I devoured this book; it was so cute. Wren is on a class trip to England and it's going horribly; she's sick for most of it. On the last day she is determined to do something right (according to her schedule and her sister), but the restaurant is closed. She runs into a cute guy, who turns out to be the crown prince. He is trying to hide from the paparazzi and she helps him escape. He gives her his phone number and tells her if she needs any help in the next eight days, to call. She misses her flight and at the airport finds out that a meteor is headed to earth and it's an extinction level event. She can't get home; she keeps getting bumped from her flights or they get cancelled, so she calls him. He agrees to meet her and they come up with a plan, but it is going to result in them traveling across Europe together. Meanwhile, the palace is looking for him. She gets arrested in Paris because someone saw them together, so she pretends to be meeting him, and shows the cops "clues" he leaves him in his instagram, so they think she's crazy and they let her go. They end up at his best friends house so he can get a fake passport. They end up at his ex-girlfriends house; she gets drunk for the first time, but she also learns about the bunker. They end up getting married in Greece, but she thinks it was fake because she thought he used his fake name. They finally get to his house in Santorini, and she called him family to save him. The pilot that was supposed to be there to get her home wasn't there, then she showed up and Wren made it home. Then the world doesn't end, but the Queen dies and Theo is now King. She gets some mail with no return address; it's their marriage certificate. He signed his real name. She is married to the King of England.  I ate this up! I will be reading the follow up!
