Once a Gentleman by Eliot Grayson

Penniless, friendless, and with nowhere left to turn after his family’s ruin, Kit Hewlett can’t afford any more disasters. When a rakish, too-handsome gentleman—and Kit’s own clumsiness—cause him to lose his position as a bookshop clerk, Kit has no choice but to accept the gentleman’s offer of employment as his secretary.
Andrew Turner serves honorably in the Royal Navy, but when ashore he wastes his fortune and his time on an endless round of drinking, cards, and…other pleasures. He appreciates his new secretary’s slim body and pretty green eyes more than he ought, but he’s also struck by Kit’s quick wit and clever mind. To Andrew’s shock, he finds himself wanting more than a tumble. But that’s inconvenient. It’s irritating. And Kit won’t bed him anyway.
Trying to convince Kit that he’s more than just a debauched wastrel takes some doing, but once desire overrides Kit’s common sense, their attraction explodes into passion. Just as Kit dares to believe in Andrew’s love, Andrew’s ship is sent on a mission to the Continent. Will separation, worry, and fear tear them apart or will love bind them to one another forever?
