Dinner for Two by Mike Gayle

Second Hand

Dave Harding's got a wonderful wife, a beautiful home, and a job he could do in his sleep...
So no one is more surprised than Dave when he hears his own biological clock start ticking. Loudly. Unfortunately, his better half, Izzy, has no nine-month plan for fat ankles or a credit line at Baby Gap. With even worse timing, the music magazine Dave writes for folds. Desperate for work, he's forced to become an advice columnist for a teen magazine.
But he's about to get a serious wake-up call.
Wading through letter after letter of adolescent angst is the last thing Dave wants to do, especially since he could use some help dealing with his own. But one letter is about to make all his little problems disappear -- and replace them with one big one.
The letter is from a teenage girl named Nicola. But she doesn't need advice about boys, or friends, or the latest fads. She's looking for her father, whom she's never met. She's looking for a man to call Dad.
She's looking for Dave.
