Do you need some help finding the next book in a series? Or do you want to browse through a series list or find some reviews other than in your newspaper or Amazon? Here are a few ideas:
www.thebigthrill.org - this website focuses on thrillers and is a monthly online magazine. It includes reviews of new thrillers and articles about the genre.
www.themysteryreader.com - this site has thousands of reviews broken down into subgenres such as police/detective, thrillers, suspense, romantic suspense (who knew?).
www.theromancereader.com - a sister site to the mystery reader site but for romances.
http://www.fantasticfiction.co.uk - this is a wonderful source especially to find books in a series.
Generally, you don't have to type in the "www" in your search. Just type in "thebigthrill", "themysteryreader", etc. and the site should come up. Happy browsing!
