No nonsense consumer psychologist, Sienna Lambert moderates focus groups to assist her clients with marketing their products to target audiences. Her newest client, Dexter Clothiers has developed state of the art men's undergarments, Best Kept Secrets, that become more comfortable the longer they're worn. Sienna interviews men from all professions and all walks of life to get their opinion on the new line. When adrenaline junkie, Vaughn Deveraux meets Sienna he takes her breath away, literally. After a run-in at a client softball outing Sienna assumes Vaughn is one of the new models for Dexter Clothiers. Vaughn tells her he's the Creative Director at the company advertising the line and jokes that he leaves the modeling in the very capable hands of his younger brother, Pierce, a retired professional football player who's had a great deal of experience with women asking questions about his briefs. Though intrigued, Sienna keeps her distance when she finds out he works with her client, but Vaughn's fun nature and zest for living prove too irresistible to ignore. Sienna's once calm, predictable life gets turned upside down when Vaughn shows her that sometimes life is better when you experience it instead of researching it--P. [4] of cover.
