One of my MFA mentors, Tibor Fischer complained about that. His debut novel, Under the Frog was shortlisted for the Booker prize and his publishers wanted more of that, but he wanted to write different things (and did). His later books tend towards darkly comic crime fiction. I recommend The Collector Collector as a good starting point.
