I think the title of this one should be Will Grayson, will grayson because the book is told in alternating chapters by two high schoolers with the same name, one of whom doesn't use upper case letters. Maybe his clinical depression and lack of self-esteem have something to do with it.
When I was reading the book, I wondered who wrote which chapters. The first Will Grayson's chapters sound more like John Green, and I'd have picked him as the author of those except maybe that's what they want me to think. Maybe Green and Levithan switched off chapters. Or maybe they switched off on styles and Green wrote the will grayson chapters.
Not that makes any difference. No matter who wrote what, it's a very funny, touching book. One of the major characters is Tiny Cooper, the “the world’s largest person who is really, really gay, and also the world’s gayest person who is really, really large.” Tiny is Will Grayson's best friend and has been since they were in fifth grade. Through a remarkable coincidence, Tiny meets will grayson, and the two fall in lust. Things get complicated because Tiny has introduced a girl named Jane to Will Grayson, whose two rules for living are these: "1. Don't care too much. 2. Shut up." Will finds himself falling for Jane, while will and Tiny are falling for each other.
Meanwhile Tiny is preparing to produce his high school musical, which, believe me, bears absolutely no resemblance to any Disney movie named High School Musical. It's the world's gayest high school musical. It's so gay that it makes Glee look like an episode of The Wire. But it's a great musical. It's about love and friendship, just like the whole book, which concludes with a performance of the show. While the ending is highly improbable, it's also eminently satisfying.
A final comment. This book has every naughty word you can think of in it. Not to mention underage drinking. Combine that with the gay themes, explicit references to gay sex, and even a couple of necking scenes with Tiny and will, and you have a book that would have sent the parents of my hometown marching on the library with torches and pitchforks when I was in high school. Times have changed, as if you didn't know, but I have to wonder if this book won't get some of that kind of attention even now. We'll see.
