“Beautiful Day,” Elin Hilderbrand 12th novel, is a bestseller in Boston (and beyond), but like all the author’s books, its roots and heart are in Nantucket. Hilderbrand has lived on the island for 20 years now, and its spell hasn’t been broken yet. The Globe talked with her over the phone as she awaited a flight to that other island, Martha’s Vineyard.
An unabashed fan of summer — and “all the trappings of the American summer,” from beaches to carnivals, from ice cream to miniature golf — Hilderbrand says she’s not offended when her books show up on lists for beach reading. “In writing about Nantucket, I ended up writing what people perceive to be beach books,” she says. Still with a steady stream of successful novels, she’s a writer worth taking seriously.
