Ada's little sister is getting married. Which should be a happy thought, right? But the once close sisters have been in a year long fight, the wedding is all the way in Ireland, and Ada is so broke that she just barely managed to get a ticket on a budget airline. And as if things couldn't get worse, said airline just cancelled her connection. Which means Ada is stuck in London with no way to make it to the wedding. Surely she's hit rock bottom? So, there's no reason for her not to spill her heart out about the over-the-top wedding, her sister's worryingly quick engagement, and the womanizing best man she's dreading meeting to a handsome also-stranded stranger at the bar. Until she realizes the stranger is headed to the same wedding. Oh, and he's the infamous best man. Now, Jack and Ada must put their simmering attraction behind them to make it to Belfast before they miss the nuptials. But between flat tires, missed trains, and suspect hostels, Jack and Ada start to question whether their feelings are worth going the distance, or just a distracting detour along the way.
