Help Me Plan My Big Book Bash

One of these days soon, perhaps next week, my novel A Spark of Heavenly Fire will be released.

Finally.

After years of sending out query letters, after enduring hundreds of rejections, after surviving three worthless agents, I found a publisher who loves my books. Mike at Second Wind Publishing recently told a group of romance writers:  “If you haven’t, you all need to read Pat’s novels — especially A Spark of Heavenly Fire. It’s loaded with multiple love stories, triangles, lost love, romantic character development, unrequited love, and even a little happily-ever-after. Thank God she’s not a romance writer — we’d all be out of business!”

Now that deserves a celebration, so . . .
 
I am going to throw a virtual launch party when the book is published, a big book bash here on Bertram’s Blog. Most such “parties” come across more as announcements than celebrations, but I would like mine to seem like a real party, a real celebration. Do you have any suggestions on how to make an online blog party fun and festive?  How do you get people to hang around for a while, not just stop by and leave a comment? Is there such a thing as an eparty favor or an eprize or a way of simulating party games?
 
Any and all help would be appreciated.
