Finally Together with the Football Billionaire Groom by Ellie Hall

Her new client was her high school crush. His new etiquette coach is the girl who got away. But giving things a second chance is against the rules.
Pippa found her way back to believing in true love after healing from a broken heart. But that’s in the past and she’s an independent, capable, modern woman. She certainly doesn’t need her parents meddling in her love life and trying to marry her off. She can do it herself. Working as an etiquette coach puts her among the social elite, including some promising prospects.
Chase Collins, the Boston Bruiser’s quarterback, gets a lot of flak for his perpetual bachelorhood, but he doesn’t want to settle down until he finds “the one.” After a team prank goes awry, landing him in trouble, he’s sent for etiquette coaching. But that’s the least of his problems because a family feud comes between him and the game.
Pippa and Chase unexpectedly meet again at a social function and their respective parents play matchmaker, urging them to say, “I do.” As it turns out, she’s his new etiquette coach and dating is off-limits. A major problem since they can’t deny their feelings for each other.
Her solution: find him a replacement fiancé. His solution: prove to Pippa that he’s changed and not the boy she once knew. They’re both stubborn and want to find love on their own, but what if their parents are right and they’re meant for each other?
