Rhiannon has a boyfriend called Justin. She desperately wants him to fulfill her needs, but he falls short in many ways. However, she is blown away by another soul that she encounters called, mysteriously, "A." A inhabits a different body every day of his/her life. A gets the opportunity to experience vastly different people's lives and to forever alter them for better or worse. A inhabits a suicidal girl, a gorgeous girl, a homeschooled boy, boys who are identical twins, Justin, Rhiannon, and more.

A and Rhiannon express their widely different experiences. Rhiannon struggles to explain what it was like to have A hijack her life for a day. A tries to convey how disconcerting it is to wake up each day in a different location with different parents in a different body with a very different life. Despite their varying perspectives, A is smitten with Rhiannon, and Rhiannon desperately wants to make this relationship work since she has never met anyone who captivates her like A. Rhiannon emails A every day to discover where he/she is and whether they can meet up. It is a tenuous love.

Another Day by David Levithan, 2015

A sequel to Every Day, this book once again displays Levithan's brilliance. I almost think that this is a book about dissociation, or Dissociative Identity Disorder. "A" inhabits so many personalities and bodies.
