In the beginning this exposure is more difficult. Nobody knows you and nobody cares...well you know, no one but your friends and family. Anyways, the point is, people have to know you to care about you and want to read your work. So you have to attend cons, speak in front of school groups, talk at club meetings, and volunteer to be on panels. Get your name and face out there and when it is familiar to others, you might get some new friends and possibly some new fans.
Here is a bit of advice on what NOT to do. Don't set up a book signing if you don't KNOW that people are going to show up to it. For the most part, random people do not stop and talk to random authors and buy their books, so the whole thing typically ends with crushing disappointment. Book signings are for later, when you're more of a known quantity. Trust me on this one.
Anyways, you never know when the opportunity is going to come or who it will be through, so don't be thrown or beg off an invitation just because it seems a little odd. It might turn out to be a better fit that you think.
