Thanks, Linda! I'm happy you thought it was a worthy continuation of Tyler Locke's adventures. Looks like you could be the first to review it on the UK Kindle store if you'd like.
I'm already working on number 4. Got great ideas for it on my research trip to England, Scotland, and France last month.
Ann, I promise it will be released in the US long before the next one comes out in the UK. When I was still with Simon and Schuster, they were considering delaying the US release of The Roswell Conspiracy until summer 2013, so at least we don't have that prospect looming over us.
