Didn’t find Fabulous nobodies at the library, but instead borrowed Lee Tulloch’s Two Shanes. Also set in NYC, it’s the intertwining story of two Australians, both called Shane (or Cheyne) & various New Yorkish characters who, well, intertwine with them in various ways. Americans can’t tell Australians apart so well, and a comedy of errors ensues, but by the end all’s well and everyone’s happily ever after.
Factual thing learned about New York: there is no good surf in Manhattan.
