which lets you look for authors similar to the name you input or find a forum or newsgroup about a particular author

I really liked the Plum series and read it side by side with the Rita Mae Brown's Mrs. Murphy Cozet Mysteries as they both kind of appeared about the same time
Liz Evans' Grace Smith might be the English version of Stephanie Plum, they are humorous
I'm not an outdoors person by any means but Patrick McManus early books and Kinky Friedmans mysteries also were enjoyable
