What would you do if the world was ending? Wren Wheeler has flown eight thousand kilometres across the ocean to discover she's the worst kind of tourist: the kind who just wants to go home. Her senior-year trip to London was supposed to be life-changing, but Wren's perfectly planned itinerary is in tatters. Then she meets a very cute boy with a posh accent who looks remarkably like Prince Theo, the British Crown Prince. With news of a catastrophic comet hurtling towards Earth, Wren and the Prince are forced into the highest-stakes journey of them all as Wren tries to race home - before the end of the world. A heart-stopping story of royalty, romance and the most frenetic race across the world
