hello i'm looking for a site to point me in the direction of a good book?

[mrmojorisin]

i'm all out of books at the mo and hate not having something on the go,so are there any sites that review new and old books and show similar genre books. I guess it would be a book club or something ,yeah?
ie. i enjoy bernard cornwells books (but have read them all), who is good who writes similar books? thanks.
