There's an interview I did with the amazing Elisa Albert up today at The Millions:
TM: Tell me what you’re reading, what you’ve been reading for the past few years, what fed into Feast Days, and what your head is in these days?
IM: Feast Days has two presiding spirits: Elizabeth Bishop and Joan Didion. Both of them are referred to in the course of the novel. Elizabeth Bishop, beyond what her poems mean to me, is inextricably bound up with the idea of the expatriate in Brazil. You can’t think of Brazil and not think of her. Didion is a more global sort of influence for me, the rotating blades of her sentences, the reach of her eye, her precise sense of the dangers of exporting Americans to far-flung locales. She puts her finger on things. Elizabeth Hardwick, in particular her masterpiece Sleepless Nights, gave me a feeling early on for the possibilities of attrition in prose, for what a slim book can do. Perhaps no writer is more significant to me than James Salter. The title Feast Days is meant as a nod toward Light Years, and also Salter’s memoir, Burning the Days. Graham Greene is another influence buried deep in the substrata of my sense of self as a writer. He’s named in the book, too. I suppose that’s to say I wear this stuff on my sleeve.
