Paper Towns 
The story is about a girl names Margo Roth Spiegelman and a boy named Quentin,and of course their friends.Quentin was only a kid when Margo became his neighbor,Quentin fell in love with her since the moment he saw her,it was kinda like love at first sight.
They became friends,they rode bikes together and then one day they saw a dead body,They panicked and went home.In the evening Margo came to Quentin window and he opened it,Margo said that she found out who the man was,he was married and got divorce so maybe he shot himself,Margo said to Quentin let's find out more about this man,Quentin replied I don't wanna get in trouble just go to sleep.Margo loved mysteries so much that she become one.
 Margo never talked to Quentin again.Many years later Quentin went to school with his friends Ben and radar(Ben was goofy and Radar was quite smart),they started chatting about prom and talking about who they can go with.Radar had a girlfriend names Angela,so he was going to go with him,Ben was alone because he was a nerd and Quentin,well he never like anyone but Margo,but unfortunately Margo had a Boyfriend and for some reason they never talked.In the evening when Quentin was trying to sleep,Margo appeared in the window and said to Quentin I need to borrow your car,Those were the first words in years Quentin has heard from Margo.Quentin said no at first but when Margo said I need you too he agreed.They were on a mission,The mission was to get revenge from Margo's boyfriend that was cheating on him.They had a lot of fun during the mission after that they slow danced and then hugged,so Quentin thought that they were going to be friends again.The next day,He told his friends about it,they didn't believe at first so they wanted to ask Margo,but Margo wasn't there,that day,the next day and they day after that.Quentin noticed that Margo left him clues the find the map of Margo so he could find her,when they found where she was,He asked his friends if they could come with him,they agreed but they said they have to be in time for prom,Angela and Margo's friend Lacey came too.When finally they found the place,Margo wasn't there,Quentin's friends left him because they could have missed prom but he stayed there and tried to find Margo,when he found her, he hugged her Margo said umm hey Quentin,what are you doing here,he replied didn't you leave clues behind for me to come and find you! Margo said yes but I didn't expect you to come and find me I just wanted you to know that I'm okay,He said I love you Margo,Margo said you don't even know me I don't know me.Afterwards they talked and Quentin bought a ticket to his town back and he did make it in time from Prom and he had fun with his friends but Margo stayed there ..
 So thing that I will change is the ending,to be honest I hated it because all the hard work Quentin done was for nothing.I would change it too Margo like Quentin back and then,both of them would go back in time for prom.But overall I liked the story.
