With Simon Wood at Book Carnival in Orange, CA, for a dual racing mystery signing!
With my agent, the fabulous Lucienne Diver.
With 3/4 of my writing group.

The rock only moved at night, when roads could be closed, traffic lights moved, wires cut, and so forth. During the day, it sat still, at the side or in the middle of a road, and waited for night. Except in my town, where residents decided to throw a party. A rock party, of course.
There were artists painting the rock and its transportation, DJs playing songs with "rock" in the title, vendors selling tee-shirts ("Bixby Knolls rocks!"), LACMA representatives handing out information, hundreds (maybe thousands) of local residents and workers. It was lots of fun, to be honest.
This is slapstick in book form. Radar Hoverlander has vowed to go straight from his life of cons, but his father reappears in his life and sends his plans and resolutions packing. The ending is grand, hilarious, over-the-top, and totally entertaining (as is the entire book). You'll laugh out loud, roll your eyes, and enjoy it immensely.
3. Have an elevator pitch. You'll use it trying to find an agent, trying to get the book sold to a publisher, trying to spread the word about it, and trying to sell it one-on-one. It's indispensable. Practice it endlessly.
