The author of The Lightning Thief and other popular titles will be the guest of honor at Poseidon's Fish Market, which will take place at the Port Plaza in downtown Olympia between 2:00 and 5:00 on Sunday, October 9. It will be an extravaganza with booths, activities, and books for sale. There is no admission charge and tickets are not required. You can just show up. However, Mr. Riordan will be signing books, and for this you will need a ticket. Tickets can be picked up at Tumwater Timberland Library. If you're a fan of Mr. Riordan, come check out this event. It's going to be quite the spectacle.
