Sweet Surrender by Nina Lane

He’s an encyclopedia of sex. She’s ready to do some research. Super-efficient Kate Darling needs lessons in love. As executive assistant to the CEO of the Sugar Rush Candy Company, Kate knows everything about organization and nothing about relationships. Then she literally falls into the arms of Tyler Stone, youngest Sugar Rush heir and notorious bad boy. After a colossal screw-up involving a pretty girl and a stolen speedboat, Tyler is facing the punishment of an actual job. His father has sentenced him to organize the company library, which is Tyler’s definition of cruel and unusual punishment. But if he can convince industrious, resourceful Kate to help him, he’ll earn his release in no time.

Kate is no fool. Tyler is an encyclopedia of sex, and she’s ready to do some research. She’ll help him with the library—if he’ll teach her about the erotic side of romance. Cataloging, alphabetizing, and metadata collide in a storm of lust, sweat, and dirty talk as Kate and Tyler get to work on both the library and each other. But when he starts falling for her, their hot affair will be one for the books.
