Talk about service! I just got an e-mail from Chuck Sambuchino who's the brains behind the Guide to Literary Agents website. He saw my post from earlier today and was kind enough to send me a direct link: http://www.guidetoliteraryagents.com/blog/How+I+Got+My+Agent+Lisa+Lawmaster+Hess.aspx.
Please check out his blog (http://www.guidetoliteraryagents.com/blog). You don't get service like this everywhere.
