Overbooked

Overbooked is a website for 'ravenous readers'. From the site:

"Overbooked specializes in providing timely information about literary & genre fiction as well as readable nonfiction. Overbooked originals include annotated lists of nonfiction, fiction and mystery books which received starred reviews, themed booklists, featured titles lists and hot lists of hard cover US fiction releases. "

It's a US site though and lists only new releases available there, but you might get some good ideas about what to read next.
