Waiting for Love by Carol Coventry

If the gossips of the ton can agree on one thing, it is that Lady Olivia Taverston will marry a Peer.
Everyone expects Lady Olivia Taverston, the winsome sister of the Earl of Iversley, to be the most sought-after debutante of the London Season. Yet Olivia cares nothing for attracting suitors. Suitors lead to marriage, and marriage means leaving behind everything that she holds dear. Not even the prospect of a love match excites her. She fell in love once. It hurt. She won’t do it again. Naturally, a lady must marry, but Olivia can’t pretend to be happy about it. Especially not after he reappears—and he’s handsomer, kinder, and more annoyingly noble than ever.

Mr. Benjamin Carroll has returned to England after an admittedly harebrained attempt to make his fortune in Canada. A failed business venture not only left him bankrupt, but also made him the adoptive father of his deceased partners’ little girl. Thankfully, he has a lifeline. Jasper Taverston, the Earl of Iversley, an old Oxford chum, has offered him the job of estate steward. The only complication is Jasper’s little sister. Years ago, her infatuation with Benjamin progressed from silly to embarrassing. Of course, it’s absurd to think she could still be carrying a torch for him. She should be grown up and married by now. Except he finds she is not. Not married, that is. She is very definitely grown up.
