If this isn't your first rodeo and you've become a bit bored with the usual shtick, you may want to try having the audience shout out (or chat out) a random page number and start reading from that point for a fixed amount of time. Pros of this method are it's something new and it gets your audience more involved. Cons are that it's hard to practice reading your whole book, and a lot might be lost on the readers thrown into the middle of the story with no context. Also, if your book has any mysteries involved, you may inadvertently give away spoilers.
Whichever method you choose, make sure you keep an eye on timing and remember to have fun! If you don't look like you're enjoying your own book, how can you expect others to want to read it?
Good Luck!
