Very good. James M. Cain is known for his noire works. I'm not sure this qualifies as one of those.
Basically, it's the story of a young woman during the Depression. Her husband loses his real-estate business and takes up with a floozy. The young woman needs to support herself and daughters. Her only real talent is cooking. Desperate for a job, she takes a gig as a waitress. Eventually she gets into the restaurant business and builds a successful business. There are many setbacks along the way—she has several inappropriate liaisons and a daughter who is 100% diva—but she more-or-less triumphs. Actually, the triumph part isn't completely clear. But with her basic grit and determination, one expects she'll get things on track. Whatever, an interesting take on the 1930s.
