As part of the Titan's Curse tour this May, I'll be giving out new T-shirts as prizes at my book signings (along with the standard Camp Half-Blood T-shirts which I will continue to distribute). The Hunters of Artemis play a major role in the new book, so it seemed only fair that the followers of the goddess should have their own T-shirts. For a chance to win one, come by any of my public book signings in the U.S. in May. A complete list of appearances is on my website here.
The shirts cannot be purchased! The only way to get one is to snag one at a Percy Party event.
