The former cop with a checkered past has made a career of recovering stolen rare books with her private detective firm. She’s level-headed, smart, cool under pressure… and entirely unprepared for her new assignment. When a centuries-old book worth an astronomical fortune disappears from Philadelphia’s Franklin Museum, Delilah is paired up with Henry Finch, a brilliant rare book librarian and celebrated academic. Their orders: Go undercover as a married couple and recover the book by whatever means necessary. Henry can speak four languages and wear a suit like he was born in Armani. But he’s never squared off against criminals. Never operated in this underground society of glamor and greed. And he’s certainly never pretended to be married to a woman who both dazzles and distrusts him. Delilah’s keen instincts are her greatest gift, but her growing attraction to the sexy librarian is messing with her head. Every feigned caress, every for-the-audience kiss only heightens the seduction, building a fire that refuses to extinguish. As the danger intensifies, so does the temptation to let their fake desire become real. With a priceless artifact at stake, can this undercover couple learn to trust each other…before it’s too late? Author’s Note: If fake marriage, closet sex, secret passages, guns and garter belts, high-society galas, mysterious code words, and danger pushes your pleasure buttons Behind the Veil is for you! less

When a betrayal leaves him questioning his career with the Bureau, consulting for Codex seems like the perfect place to hide. But he certainly never expected to see Freya again.

Now these enemies are forced to play nice as they go undercover to infiltrate a secret society. It’s a dangerous world of power, wealth, and shifting alliances. The higher the stakes, the harder it is to resist the true reason behind their rivalry. But surrendering to years of pent-up lust is a direct threat to their mission…and their safety.
