Not directly. There's a service called
Any New Books? which does weekly notifications of new books in certain genres. Since most e-books come out at the same time as the print editions, that could be helpful.
Since you're interested in specific authors, I'd suggest you visit the authors' web pages. Most of them have ways to get notifications, whether by email, Twitter, Facebook, or all of the above. They have a strong interest in keeping their readers informed about their latest releases.
