On the Way to the Wedding (Bridgerton, Bk. 8)

Unlike most men of his acquaintance, Gregory Bridgerton is a firm believer in true love. He'd have to be an idiot not to be: all seven of his siblings are happily married. Gregory figures he is just biding his time until the right woman comes along. And so, when he first sees Hermione Watson, he knows with every fiber of his being that she is meant to be his. But through Hermione's closest friend, Lucinda Abernathy, he finds out that Hermione is desperately in love with someone else. Sadly, by the time he figures out the right girl is actually the wrong girl and that the right girl was Lucy all along, it's too late. Lucy is to marry another! Now, on the way to the wedding, Gregory must risk everything to ensure that when it's time to kiss the bride, he is the only man standing at the altar.
