She's the One by Cathy Kelly
Meet Dee - an agony aunt on an Irish newspaper, with more problems than her readers. She's engaged to Gary, but he's far from perfect and his mother is driving her crazy...Now meet Isabel - her husband has just lost everything in a business deal and Isabel has gone home to Dublin with ther two teenage girls. Getting the job as women's editor on the paper would be a dream come true for both of them, but they can't both get what they want...or can they?
