THIS REVIEW CONTAINS SPOILERS! 
 ******************************************** 
 Hmmm. 2.5 stars. This is the story of how straight, male, small-town Logan falls for new girl Sage, then shuns her when he finds out she was born a boy, then slowly patches up their friendship and eventually their romance. 
 Pros: 
 Boyer: I haven't grown up or lived in a small town, but I've always wondered how people get "stuck," both physically and in their intolerant mindsets, and I feel like the description of Boyer was dead on. (I was pretty much picturing Dillon, Texas, from "Friday Night Lights.") 
 Logan's voice: so straight and male I didn't like it at first, but from what I know about guys, this is quite often how they think. No overthinking, nothing flowery, just the facts. And quite funny at times. 
 Cons: 
 Jacket blurb: Gives away that Sage is a boy. Logan doesn't find out till p. 99. That's a long time to read his comments about her height and broad shoulders. It makes him sound really dense and is frustrating as the in-the-know reader. 
 Sage's parents: Really? I understand she was supposed to be misunderstood and a cause for shame in her parents' eyes, but that could have been portrayed in a much more multi-dimensional way. 
 Sage's hormones: In contrast to I Am J, in which the plot centers around J's efforts to get the therapy required to start taking hormones, this book doesn't even mention them until Logan sees Sage in a bathing suit and his head almost explodes. Yes, she has large, attractive boobs, and Logan can't let it go until Sage finally admits, in a conversation that takes up all of two pages, "I order [hormones] from Mexico." She conveniently has an account with her name on it and her parents, in spite of keeping her so physically and emotionally isolated that it borders on abuse, know about this and let her order drugs illegally through the mail. What the what? Are these the same parents? 
 This flippantly-treated turning point really bugged me. It seemed like a plot device designed to avoid the questions a real transgender teen would have about hormones, legality, payment, therapy, age, effects, etc., and instead make it easy for Sage to conveniently have a female body that Logan could find "hot" so their relationship could get physical. (But again with the being true to how most guys think, perhaps?) This, more than anything else, is why I might give this to a straight guy reader, but not a transgender teen. And what does that say? 
 As a caveat, in the Author's Note, Katcher does say that he interviewed "real-life Sages" and that no one should endanger themselves by taking illegally-obtained hormones. 
 Favorite quotes: 
 "I felt a bizarre mixture of friendship, lust, fear, pity, lust, confusion, panic, and lust." 
 "I could visit her, but she lived under someone else's strict rules. It didn't matter how much I cared for her; she feared the warden more than she liked me." 
 "I'd spent nearly two months thinking warm and fuzzy thoughts about Sage. If I was going to hate her, it would take some work." 
 "Shame never dies in a small town." 
 "He probably hadn't meant anything by it. When you're a teenage guy, you pepper your conversations with f*ggot, butt munch, and douche bag. In the strange world of male bonding, questioning someone's sexuality and hygiene was a way to demonstrate friendship and camaraderie." (gross!) 
 "There's a fine line between being hurt and being an a**hole." 
 "There was no way I could ever be relaxed around this person again. To me, Sage would never be just Sage. She'd be Sage-the-boy-who-pretended-to-be-a-girl-and-who-I-kissed-that-one-time. No friendship could survive that many hyphens." 
 "[Brenda] didn't feel comfortable swimming. She was the only girl I ever knew whose bathing suit had sleeves."
