Ninety Degrees - A Precursor to Small Circles by Megan Duke

Ninety Degrees is the story behind Silas McFuller's senior year at Chattanooga Prep. He and his best friend, Charleigh McAfee, have never cared about grades or ACT scores. Their drive stems from creativity and pushing the boundaries when it comes to the arts and the world around them. They've got one year left of high school, and they want to make it count. For Charleigh, that means crossing into dangerous territory alongside a rebel with a southern drawl. For Silas, it means letting go of reasoning and finally letting his true self shine. Readers of the Small Circles books know better than any that life is short, and within that small spanse of time, it's okay to be happy.
