It’s obvious that Jill A. Davis was once a writer for David Letterman — her first novel, Girls’ Poker Night, is filled with the sardonic humor he exemplified. She deftly applies her talent to the subject of love in New York City — specifically, the love of writer Ruby Capote for her boss, Michael Hobbs, as seen through the weekly poker nights she holds with her four dysfunctional girlfriends. The only potential problem with the novel — having an affair with the boss — is eliminated by the fact that this practice was accepted on Letterman’s sets, so watching Ruby and Michael wash every bit of their laundry in full public view is an absolute delight.
