Looking for a book! I don't remember the name

[Ludmila]

Hi!
My name is Ludmila and I'm from Argentina.
I'm looking for a book where the girl gets pregnant at highschool, she run away, don tell anyone about the baby and become a famous thriller writer.
She has to return to her old town and meets the baby's father and has to reveal the truth.
That's the summary.

Anyone can help me????

Thanks and sorry for the bad grammar
