Read quality book reviews. I would especially recommend the New York Review of Books and the London Review of Books, but there are dozens of long-form journals of this kind.
Most newspapers also have book review sections, as do many academic journals.
Presumably if you're interested in someone or something, you can also simply peruse the internet to see what's out there, i.e. you can start with your interests rather than with what's popular or well-advertised.
