Sophia and Camila have been the best of friends for a long time now - since first grade! They do EVERYTHING together. They like the same things, and they always have fun! So imagine Sophia's surprise when Camila starts spending more time with Christabel, and it's interfering with Sophia and Camila's time together. All of this change is hard, and Sophia finds herself wondering why. Does this mean Sophia did something wrong? Does it mean Camila likes Christabel better? Sophia finds herself thinking... I LOST MY BFF. Sophia decides to try some different strategies, and with help from her mom, starts to figure out how friendships change over time. Through honest conversations and open-mindedness, Sophia, Camila, Christabel, and Jewel soon learn that it's okay for friends to have other good friends, and not everyone needs to like to do the same things all of the time. If they are kind and respectful toward one another, their friendships can grow and change. This quick-read chapter book is part of the Navigating Friendships book series, which is great for students in grades 4 through 7 who are struggling with changing friendships, learning about self-advocacy, and figuring out how to get along with others. 40 pgs.
