"It Ends With Us" is a very deep and realistic book about an abusive relationship. Lily the main character, has a father who was abusive to her mother, and then ends up being in this type of relationship herself. 
 The book makes you realise how people can cling onto a person they love even if they have been subjected to domestic violence. The plot shows how difficult it is for someone to walk away from an abusive relationship, as they remember the good times they have had with that person. The situation is also made harder when you are a child growing up and have parents in an abusive relationship. 
 From the story we can learn hard it is for the victim to explain their situation to friends and family. We also see how hard it is for the victim to talk about the situation with their partner. 
 Colleen Hoover was very brave writing this book, which she based on her own parents' abusive relationship. Very well written.
