Shocker: Copywriter writes book ... set in advertising.

Like the novel "E" by Matt Beaumont this fictional book is set in the advertising business, but "Truth in advertising" also deals with some serious issues. Finbar Dolan is lost and lonely, had feet so cold he called off a wedding, and now has to call off his vacation to write and edit a super bowl spot about diapers in record time. Then things get worse. His once abusive father falls ill, his siblings do not intend to visit, and just what in the hell is Finbar really doing with his life? Shilling diapers!
