The Loser's Guide to Life and Love: A Novel (June 2008) by A. E. Cannon
The main character Ed is losing his hearing in one ear. I'm not adding this book to my 100+ and Counting list since Ed is hardly a hard-of-hearing character; however, the author has earned praise along with several awards (including the Delacorte Press Prize for a First Young Adult Novel; an ALA Best Book for Young Adults and an American Bookseller Pick of the List; and 100 Best of the Best Young Adult Books of the Past 25 Years) so I think I should at least recommend the book.
Ordinary, boring Ed works a loser summer job at Reel Life Movies, where he doesn't even have his own name tag. He's stuck with "Sergio." Ed's only consolations are his two best friends. Shelving DVDs isn't so mind-numbingly dull with Scout cracking jokes, and after hours Ed hangs out with the superbrain, Quark. Life starts to look up when the girl of his dreams saunters into Reel Life. Ed knows he doesn't stand a chance . . . but maybe, just maybe Sergio does. All he has to do is pretend to be a smoldering Brazilian stud for the rest of his life. Simple, right? But . . . Ed's new dream girl has her own secrets, Scout wants to be more than Ed's best friend, and his buddy Quark wants Scout for himself.Star-crossed crushes make for hilarious misunderstandings as Ed guides his life toward disaster in this fresh, contemporary twist on Shakespeare's Midsummer Night's Dream.
