Greeted as the First Great Millennial Author, and Wary of the Attention

Her mass-market success is clearly still a little disorienting. “Light and sparkling is the phrase that has been used,” she said. “I can’t complain if people think it’s sparkling, but then there’s a sense that wasn’t what I set out to do.”

.. She found her tribe as a competitive debater — at 22, she was the top debater in Europe — and settled into what she would later describe as “an analytic way of living.”

.. They are battered, as well, by economic conditions. The 2008 financial crash, and its catastrophic effect on Ireland’s young people, hangs like an invisible backdrop to all of Ms. Rooney’s fiction. Her own friends, after receiving prestigious degrees, took retail jobs, or went on welfare, scrambling to pay exorbitant Dublin rents.

“In my parents’ generation, or even before that, people who are in their 30s or 40s, you’d go to college and it was easier to get a job in one of the big law firms, and you’ll be set up — you’ll be able to get a mortgage,” said Ms. Rooney’s partner, John Prasifka, 25, a high school math teacher. “Our generation is seeing that’s not worked out for us.”

Earlier generations may have naturally shed their leftist beliefs as they lofted into the middle class, he added. But with their cohort, he said, it is difficult to see that happening.

.. For 10 years, Ms. Rooney has delighted in Twitter, trafficking in cerebral self-mockery (“♫ getting into lengthy Facebook wars about Greek debt / using words like “creditors” and “Eurogroup” in my actual free time / why ♫”); earnest declarations (“the Irish state has always been organized on the unpaid labor of women”); and too-cool-for-school banter (“this New Statesman piece from last year is so bad I laughed until I literally wept.”) Ms. Rooney even gave her character Frances, in “Conversation With Friends,” a “Twitter voice,” which she described as “a tone of casual self-revelation that deprives others of the ability to criticize.”

.. During an interview in Dublin, she worried aloud that novelists are over-glamorized, and said newspapers should write more profiles of nurses or bus drivers.
