When first love goes wrong, it can lead to a rancorous rivalry…and a second chance to make everything right again years later… When newlywed Lord and Lady Felcourt invite their respective families and friends to spend the summer at their country estate, Hawthorne House, no one suspects that the groom’s brother, Mr. Grayson Hawthorne, and the bride’s brother, Lord Charles Aspenden, Viscount Broxbourne, have a history together…and that history isn’t good. The two former lovers are at each other’s throat almost from the moment the party begins. But when the bride and groom have a falling out that could end both families’ chances for lasting happiness, it’s up to Grayson and Charlie to either patch things up between the bride and groom or split them up and go their own separate ways for good. Which will it be? Vanquished by a Viscount is an enemies-to-lovers, second chance, MM romance that involves two men who love to hate to love each other, an archery competition, being stuck in a carriage in the rain, the arrival of a steamy figure from the past, and healing bruised hearts.
