This book is just the summer contemporary book that I was looking for. The plot was interesting. A group of girls find a list of who they should date before they turn 21. This causes all sorts of problems! The writing style was fun, free and funny. There were a few main characters which I liked. The plot was easy to follow, with multiple twists and turns around each corner. The friendship element at the start was brilliant. A group of five girls moving in together at the start of their second year of university. This was SO relatable to me as I was in this exact situation. They agree that they will not let any of their love lives get in the way of their friendships. There are 5 perspectives to follow - so be aware that you will be changing between girls every few chapters. A light and joyous read! Great for the summer.
