Queen of Diamonds — Sandra Cox

Logan Hunter is a bestselling author with a penchant for the ladies. Kendall Theron, his efficient publicist is prim and colorless -- at least on the surface. Beneath the proper facade is a woman who will do anything to protect her family, even if it's not quite legal.
Kendall, knowing her boss's propensity for the fair sex, has replicated herself into a lady who should hold no appeal for the charismatic charmer she works for. She's even added a Mrs. in front of her name for an extra layer of protection. If her boss ever turns those sharp eyes on her, if his curiosity is unleashed and he digs up her secrets, the results could mean jail time.
It's taken Logan Hunter nearly three years to discover there's more to his employee than meets the eye. An unplanned kiss that ignites them both has him looking at his publicist in a whole new light. He soon learns that the woman he thought he knew doesn't exist, her persona an illusion. Everything she's told him is a lie and he's determined to find out why.
