A NEW YORK TIMES BESTSELLER A TikTok sensation, this rom-com about a young woman who agrees to fake date a colleague and bring him to her sister's wedding has "everything you could want in a romance" (Helen Hoang, New York Times bestselling author).Catalina Martín desperately needs a date to her sister's wedding. Especially since her little white lie about her American boyfriend has spiralled out of control. Now everyone she knows--including her ex and his fiancée--will be there and eager to meet him. She only has four weeks to find someone willing to cross the Atlantic and aid in her deception. New York to Spain is no short flight and her raucous family won't be easy to fool. Enter Aaron Blackford--her tall, handsome, condescending colleague--who surprisingly offers to step in. She'd rather refuse; never has there been a more aggravating, blood-boiling, and insufferable man. But Catalina is desperate, and as the wedding draws nearer, Aaron looks like her best option. And she begins to realize he might not be as terrible in the real world as he is at the office.
