I have 14 copies of Storm Chaser left. That shouldn't be a problem: I only sold 15 copies at my first book signing, and that's the one where all the relatives showed. If I do run short, it'll likely be more of a problem for the signing the next Friday, at Freedom Acres In Cromwell. If worst comes to worst, I'm sure some of the retail places in Albion that have copies up for sale would let me borrow a few back until the next shipment comes in.
Having too many customers is a problem all writers should have!
