Is it illegal or breach some kind of trademark law to name my home business after the title of my one of my favorite books?

I guess the title speaks says it all. I have had a small home-based business for a couple of years and although I never really made much money from it other than a couple of hundred dollars a year, I never really put much energy into developing it either until now. So I recently got an application for a NYC tax ID number so I can officially start this business but I need a name for it. I started thinking of a name and immediately the title of one of my favorite books by Alice Walker sprang to mind. The name is perfect in every way for the type of business I have and I wanted to know if I could legally use the title of the book for my business or will I get in trouble? Does it violate any type of copyright or trademark? How do I find out?
