Lacey Terwilliger's shock and humiliation over her husband's philandering prompt her to add some bonus material to Mike's company newsletter: stunning Technicolor descriptions of the special brand of "administrative support" his receptionist gives him. The detailed mass e-mail to Mike's family, friends, and clients blows up in her face, and before one can say "instant urban legend", Lacey has become the pariah of her small Kentucky town, a media punch line, and the defendant in Mike's defamation lawsuit.

Her seemingly perfect life up in flames, Lacey retreats to her family's lakeside cabin, only to encounter an aggravating neighbor named Monroe. A hunky crime novelist with a low tolerance for drama, Monroe is not thrilled about a newly divorced woman moving in next door. But with time, beer, and a screen door to the nose, a cautious friendship develops into something infinitely more satisfying.

Lacey has to make a decision about her long-term living arrangements, though. Should she take a job writing caustic divorce newsletters for paying clients, or move on with her own life, pursuing more literary aspirations? Can she find happiness with a man who tells her what he thinks and not what she wants to hear? And will she ever be able to resist saying one... last... thing?
