After finishing the novel

I would like to ask Nick Hornby:

Is the book based on a true story?
Why do you use the future in the book?
Why did you write about a pregnancy of a sixteen year old girl?

It mainly treats of the pregnancy of a 16 year old girl, Alicia, in the book. But I enjoyed reading the book because Nick Hornby explicates this theme exciting, although it was mostly the same.
I recommend the book rather to youths than to adults because the parents maybe had or have got their own problems in the past or at the moment. So they could mean the story is written surreal.
In my opinion the End is very good because it isn`t a normal Happy End like in many films or books. The Ending isn`t immediately predictable and after reading you end with a good feeling.
