I was talking with the employees at Mysterious Galaxy and discovered Brandon Sanderson was coming to do a signing on Feb 6, but it will be a ticketed event and to get tickets you need to purchase the new Wheel of Time book there, which goes on sale Tuesday at 10am. Not sure if there is any other way to get a ticket to the event, sounded like it was first come first serve. The book will probably be about $10-$15 more expensive than at Barnes and Noble, but this is Sanderson's only planned San Diego signing for this book tour.
From his website:
Date:[masked] Time: 7:00 pm-10:00 pm
Place: Mysterious Galaxy Bookstore
Address: 7051 Clairemont Mesa Blvd. Suite #302
San Diego, CA 92111
Notes: This is a numbered event. Numbers for the signing line are available with purchase of A Memory of Light from Mysterious Galaxy, on sale beginning Tuesday, January 8, at 10 a.m.
If you are planning to attend the event, please do not place your order through the website, as all such orders are handled after the event. Instead, please call the store and purchase the book over the phone (or in person? call them to make sure) on or after the on-sale date.
I am going to try to get there a little early, I will most likely have my 18m old.
