Oh, what to say about this novel?!?! 
 I'll start at the end, with the acknowledgments. Author David Levithan stated that the inspiration for EVERY YOU, EVERY ME was a single photograph found on a refrigerator door. He decided to start writing, and along the way he was sent a series of pictures by photographer Johnathan Farmer. One by one, without previously knowing the subject matter or intention, Levithan wrote around each photograph, not exactly knowing the shape or direction his novel would take next. The final product, between Levitan and Farmer, was this novel, EVERY YOU, EVERY ME. 
 It's a fresh, fun, and fabulous concept, but how well does it play out in actuality? 
 Moving to plot, the story centers around a character named Evan who seems to be on a slow spiral towards (deeper) madness. His best friend Ariel is missing, and Evan seems to hold himself responsible. The reader is essentially in the dark as Evan details his pain and angst through a series of short, stream-of-consciousness chapters that really do little more than describe his pain, guilt, and confusion surrounding Ariel. 
 One day, though, Evan discovers a photograph -- and then another appears, and another. The photographs tie into Ariel's life, often showing her image or events that only she would recognize or emotions that only she would understand. As the photographs progress, they become almost threatening, as if Evan is being stalked by someone or something who holds him personally responsible for Ariel's disappearance. The reader follows Evan through his descent as he struggles to find the photographer and to make peace with the past. Only at the end do we ever discover what really happened to Ariel. 
 I did enjoy the general idea of the stream-of-consciousness novel driven by photographs, but my thoughts are mixed as to how much I enjoyed the actual execution. I think I'd recommend that a reader not go into this for the who-done-it aspect of the story. EVERY YOU, EVERY ME is not a mystery novel. It's not particularly climatic, and the discovery of the true identity of the photographer was little more than a let down. So, as far as rating this novel in terms of the progression of plot points, I'd probably give it about two stars for the story. 
 However, the uniqueness of format did a lot to redeem the story if the reader instead considers it a narrative of emotion -- pain, guilt, confusion, anger, and forgiveness all play a role in EVERY YOU, EVERY ME, and I'm positive that the more angsty side of my teenage self would have adored every line of raw emotion that was detailed in the text. The (extremely) short chapters keep the story moving, although they do have a tendency at times to feel choppy. Once I read the acknowledgments at the end and learned about the "making" of the novel, it actually made sense that Levithan had no idea how the story itself would end -- it does tend to read that way a bit, I think. And the endless sentences with lines stricken through the words do tend to get a bit tedious. 
 I think I'd definitely recommend EVERY YOU, EVERY ME to fans of modernistic writing formats, to hipster photographers, and to (possibly) younger readers who are likely to appreciate the angst that permeates through the character of Ethan. For those looking for the more "mystery" aspect of the novel, I'd recommend you hold off. There's just not enough here to fully satisfy.
