Romancing the Tycoon (The Colby Agency)

More than anything else, Amy Wells wants to be a Colby secret investigator, not some administrative assistant filing paper for the best in the business. She knows she'd be good at it. Driven. Daring. And with a heap of self-confidence, she has what it takes to bring down the bad guys. Now, if only she could convince her boss...But when Amy's entangled in a case of mistaken identity, she suddenly finds herself on her first assignment-figure out what makes gorgeous oil tycoon John Robert Calhoun IV tick. Out of loyalty to his father-and with the country's oil industry at stake-he's about to agree to an arranged marriage to seal the merger of a lifetime. But what skeletons is he hiding? And what should Amy do about her attraction to the Texan cowboy who's wrangled her heart?
