Did someone say John Fante?
I always recommend Ask the Dust for someone looking to get into Fante. It feels like he had really perfected his short, punctual style by that point... Wait Until Spring, Bandini is also good, as is Full of Life (his "cash-in" novel), but to really get a feel for Fante's writing and characterization, Ask the Dust is his greatest... In fact, it may be time for me to re-read it...
As a postscript... the two short story collections are also well worth the read. The Wine of Youth (collecting his first collection Dago Red, along with some others written after Dago Red was published in 1940) is particularly good, but most of The Big Hunger is good too. But read Ask the Dust first. Please. For America.
