Avery, a former plus-size model, now owns Plus-One, a designer boutique in downtown Franklin, Tennessee. She receives a letter from her landlord's attorney, informing her that rent is going up. She can't afford the extra money. She writes back, sending a fiery, spirited letter that she later fears will get her evicted.
Mason is a multi-millionaire, businessman, and Avery's landlord. He's still hurting from his divorce and bored by the hordes of women that grace his arm during his social events. When he reads Avery's letter, he is intrigued and wants to meet the woman who would challenge him to stop hiding behind his attorney.
Mason is instantly attracted to the curvy beauty with the sassy mouth. He makes her an offer she can't refuse. Be his plus-one at social events, and he will waive the increase in her rent for the coming year, but what if Avery wants more?
