Quentin and Margo are in the same class. Even though they were once such good friends, the contact seems to be watered down. Quentin has been in love with Margo since they met. Quentin seems invisible to Margo.
One evening, Margo climbs in through Quentin's window. Together they start an adventure to get revenge on some people. This is the beginning of an exciting story.
The next day Margo does not come to school. She disappeared. When Margo disappears she always leaves little hints. Quentin will look for these hints and maybe he can find out where Margo is. He has done some research and he thinks he knows where Margo is. Together with a few friends, he takes a road trip to Agloe, the place where Quentin thinks Margo is.
They find her at a farm. They just never expected she wouldn't want to be found. But that is the situation they are in now.
Quentin's friends are angry with Margo. If she didn't want to be found, they wouldn't have had to go to all this trouble. They go to the hotel angry and they leave tomorrow. Quentin will check tomorrow if he is going with them or he stays here with Margo.
Quentin stays with Margo. In the following days, they talk a lot with each other. About their past, but also about the future. Margo doesn't want to go back to her old life just yet. That is why they both decide to go their separate ways.
