Summary so far

Here's a short summary of the events until the 16th chapter:

In the novel “Slam” written by the British author Nick Hornby, the 15-year old main character Sam tells out of the future about his life: the life of becoming a young father.

Sam is a normal teenager, skater and lives with his mother in London. The circumstances in his family are pretty involved: After the divorce of his parents Sam gets weak and feels misunderstood. Neither his mother Annie, that doesn’t cope with the life after her young pregnancy, nor his father Dave, the immature, patriotic grouch, embody persons Sam could talk to. Instead of this a poster of world famous skater Tony Hawk, Sam’s idol, has to suffer for Sam’s problems and questions.
One day Annie wants Sam to go with her to a birthday party of a friend of hers. There Sam gets to know Alicia, the daughter of the hosts. Alicia and Sam soon fall in love with each other. But one time they sleep with each other, Sam makes a mistake by not using a condom. From now on Sam is afraid of the possible consequences of his action, until, on his 16th birthday, Alicia lets him know that she’s late with her period. Sam’s nightmare gets reality. He wants his old life back and doesn’t want the future to arrive.
He leaves Alicia in the abandon with the whole situation and runs away to Hastings.
One more reason for Sam’s escape is that Sam suddenly awakes in the future. He thinks that this should be a lesson taught by Tony Hawk because of Sam’s turning his back on him before.
This future is really oppressive for Sam: His mother is pregnant, Alicia is ugly and he doesn’t know how to handle the baby called “Roof”. In this future jump Sam meets his friend Rubbish, who tells him that after the birth of Roof, Sam has disappeared out of normal life.
Now Sam knows that he definitely doesn’t want living such a life.
In Hastings everything goes wrong and he notices that a baby couldn’t be that terrible. So, Sam decides to go back home.
Meanwhile his mother has called the police and Sam notices happily that everybody has worried about him.
Nevertheless nothing has changed: Alicia calls on him and the both are informing Alicia’s parents about her pregnancy. Her parents are really stunned and they’re saying that it’s all Sam’s fault, because of the history of his family (his mother’s young pregnancy). Finally everyone summons up and decides to support the young parents.
Sam tells about the gladness after the first scan of the baby, the problems in the NCT classes, where no one is the same age as Alicia and Sam, Mark, Annie’s new boyfriend, moves in and Sam gets a better relationship with Alicia’s parents.
When the moment comes Sam has already experienced because of the future jump, everything is not that bad as it has seemed before: Alicia is no more ugly but “tired”, his mom is happy and also everything else is just “appropriated” to the situation.
But Sam gets ones more whizzed into future: There’s Emily, Sam’s little sister, he’s no longer together with Alicia, he hadn’t given up skating and he loves Roof and occupies himself with him.
In reality again, because of Annie’s pregnancy, Sam and his mother get more like “friends”. Then the day of Roof’s birth comes: Alicia’s mom Andrea tries to be nice and calms down everybody. Sam is really confused in his feelings and doesn’t know if he wants Roof or not. But when the baby finally arrives even Sam is really happy.
The day after, Sam moves to Alicia but doesn’t feel comfortable living with persons he doesn’t even really love.
However the relationship between Sam and Alicia gets better but when the ex of Alicia, Jason catches Sam by saying that he is Roof’s father, Sam is for one moment something like relived not being a father…
