The Marrying Type by Megan Morgan

Need a date? Or a temporary boyfriend? How about a husband in a hurry? The professionals at SASS—Singles Arrangement Service Specialists—are here to help.

Libby Dawson has spent her life under the crushing thumb of her controlling father. She wants to escape, which would be easier if she had her half million-dollar trust fund first. However, she can’t have it unless she’s married by twenty-three—six months from now.
Blaine Parker is a savvy but disillusioned stockbroker. Tired of the cutthroat business world, he’s used his genius financial skills to secure most of the funds to retire by thirty. He just needs one more investment to get out forever—and he doesn’t mind selling himself for it.

Brought together by SASS, Libby and Blaine make a complimentary team. However, attraction and emotion—including love—isn’t a promised part of the deal. They soon discover it’s just a bonus.
