CAMBRIDGE, MASS.
Junot Díaz leans his shoulder against a crammed bookshelf in the living room of his apartment near Harvard Square, propping one argyle-socked foot against the other. He looks slighter, wiser and wearier than Yunior, the alter ego who stars in many of Díaz's short stories.
Still recovering from surgery in June for the spinal stenosis that gave him excruciating back pain, he now spends some of his time in a new leather recliner bought for this purpose.
At the moment, though, the Pulitzer Prize-winning writer of "The Brief Wondrous Life of Oscar Wao" is standing, the better to expound on love.
"To be truly in love we must be found out," he said. "The one place where you really have to practice transparency is, obviously, with that person, because without that there is no love. You have to lay down your shield. That's why so many dudes are bad at it. Because we're told vulnerability is the antithesis of masculinity. And you wonder why so many of us have trouble."
Girl problems are something Yunior -- who, like Díaz, grew up hardscrabble in a working-class Dominican immigrant family -- has plenty of in the author's new story collection, "This Is How You Lose Her" (Riverhead, $27), a followup to his first book, 1996's "Drown." Díaz comes to town Sept. 18 as the first guest in this season's Talking Volumes series at the Fitzgerald Theater in St. Paul.
Díaz's conversation is literate/street, like his writing -- words like "fulgurating" and "atavistic" pop up between Spanish slang, F-bombs and the adjective "dope." He's a word nerd who once delivered pool tables for a living, a kid from a macho 'hood who favors geek-chic specs. He's down with the traditions of his people from the "DR" (Dominican Republic), and he's an American-as-"Star Wars" sci-fi fanboy. He's a cultural amalgam, the kind of American who most accurately represents what being an American now means.
And it's impossible, he says, to separate the influence each piece of the pie has on his attitudes and writing.
