The main conflict in the story All Fall Down is that the main character Grace has a hard time dealing with her mothers death. Throughout the story Grace has an internal conflict dealing with her mother's death, she can't come to the conclusion of what actually happened to her. It leads to her accusing innocent men of killing her mom, which leads into another main conflict in the story where people aren't believing Grace, that a scarred face man shot her mom.
In the rising action, Grace goes to the ball with her grandfather. When she goes looking for Alexei she sees the scarred man talking to someone in an office, she then tries to leave but Noah sees her and asks what's wrong. Grace goes on to tell him what's wrong and he believes her, but her Grandfather and Mrs.Chancellor did not, this goes into the conflict within the story.
After Grace sees the scarred face man and talks to Noah about it, they get Megan to help search for him with her hacking skills. They get the guest list from the ball and with the help of that, they look for the man.
The climax of the story is when Grace finds her grandfather playing poker with... the scarred man. She finds out that they are friends and his name is actually Dominic Novak. This part of the story raises tension because Grace doesn't really know what is going on anymore- her grandfather is friends with "Dominic," and nobody is believing her about anything anymore, so the readers are trying to figure out what will happen next.
Grace and her friends start to spy on Dominic once they find out who he is and they do this by planting cameras in his house and following him around. When this was all going on, Grace's grandpa threw a party and they spied on Dominic there. At one point Grace thought that he had a gun out and was going to kill someone so she jumped on him, to find out the it was just his phone he was holding. That then led into the resolution.
What did I just do!?
Grace learned that Dominic worked as the head security for the prime minister, and when Grace's mom was still alive the prime minister ordered him to kill her. But he didn't and wouldn't have been able to, because he was actually in love with her. One of the last things that was a little confusing but became clearer towards the end for the readers, was that Grace was actually who shot her mom, she just blocked it out of her memory because she didn't want to believe it.
